Te recomiendo que mires arquetipos para guerrero; ahora no recuerdo los nombres en español, pero en el Combate Definitivo (Ultimate Combat), está, por ejemplo, el Brawler y el Cad (te los copio):
------------------------
Brawler (Archetype)
All melee is up close and personal, but some warriors bring it as close as they can get. Brawlers can be found anywhere, among all races and societies. A brawler could be hired muscle in a tavern, a local crime syndicate enforcer, or a hotheaded recruit among the ranks of a baron's guard. Often brawlers' in-your-face attitudes are as powerful as their tactics.
Close Control (Ex): At 2nd level, a brawler becomes skilled at forcefully moving his opponent around the battlefield. The brawler gains a +1 bonus on bull rush, drag, and reposition combat maneuver checks. The brawler also gains a +1 bonus to CMD when attacked with the bull rush, drag, and reposition maneuvers. These bonuses increase by +1 for every four levels after 2nd (to a maximum of +5 at 18th level). This ability replaces armor training 1.
Close Combatant (Ex): At 3rd level, a brawler gains a +1 bonus on attack rolls and a +3 bonus on damage rolls with weapons in the close weapon group. Both of these bonuses increase by +1 for every four levels beyond 3rd (to a maximum of +5 on attack rolls and +7 on damage rolls at 19th level). This ability replaces weapon training 1 and 2.
Menacing Stance (Ex): At 7th level, a brawler constantly harries and distracts his enemies. While adjacent to the brawler, enemies take a –1 penalty on attack rolls and a –4 penalty on concentration checks. These penalties increase by 1 for every four levels after 7th level (to a maximum of –4 on attack rolls and –7 on concentration checks at 19th level). Creatures do not take these penalties if the brawler is dazed, helpless, staggered, stunned, or unconscious. This ability replaces armor training 2, 3, and 4 and armor mastery.
No Escape (Ex): At 9th level, taking a 5-foot step out of the area of a brawler's menacing stance or moving out of the area of a brawler's menacing stance with a withdraw action provokes an attack of opportunity from the brawler. This ability replaces weapon training 3 and 4.
Stand Still: At 13th level, a brawler gains Stand Still as a bonus feat, even if he does not have the Combat Reflexes feat. If the brawler already has the Stand Still feat, he can take any other combat feat instead. Furthermore, he gains a bonus equal to 1/2 his fighter level on combat maneuver checks when using the Stand Still feat.
Weapon Mastery (Ex): A brawler must select a close weapon for this ability.
------------------------
Cad (Archetype)
In combat, most fighters have some sort of code of honor. Some believe that one should not kick enemies when they are down, or should limit use of other such dirty tricks to the most dire of circumstances. The cad places no such limitations on himself. Battles are for winning, and anything that gives the cad the upper hand against his enemies is a legitimate tactic. No trick is too treacherous if it leads to victory.
Weapon and Armor Proficiency: A cad is not proficient with medium armor, heavy armor, or tower shields.
Skills: Acrobatics (Dex), Bluff (Cha), Escape Artist (Dex), Sleight of Hand (Dex), and Stealth (Dex) are class skills for a cad.
Dirty Maneuvers (Ex): At 2nd level, a cad becomes skilled at deceiving and discomfiting his opponents. The cad gains a +1 bonus on disarm, dirty trick, and steal combat maneuver checks. The cad also gains a +1 bonus to CMD when attacked with the disarm, dirty trick, and steal combat maneuvers. These bonuses increase by 1 for every four levels after 2nd (to a maximum of +5 at 18th level). This ability replaces bravery.
Catch Off-Guard: At 3rd level, the cad gains the Catch Off-Guard feat. This ability replaces armor training 1.
Payback (Ex): At 5th level, a cad gains a +1 bonus on attack and damage rolls against any creature that has attacked the cad since the beginning of his last turn. This bonus increases by +1 for every four levels beyond 5th (to a maximum of +4 at 17th level). This ability replaces weapon training 1, 3, and 4.
Deadly Surprise (Ex): At 7th level, when a cad hits an opponent that is denied its Dexterity bonus to AC against him with a weapon or unarmed attack, he may attempt a dirty trick combat maneuver as an immediate action as part of the attack. This ability replaces armor training 2.
Razor-Sharp Chair Leg (Ex): At 9th level, as a swift action, a cad may alter the type of damage dealt by an improvised weapon to bludgeoning, piercing, or slashing damage. In addition, the cad has a critical threat range of 19–20/×2 with any improvised melee weapon. This ability replaces weapon training 2.
Craven Combatant (Ex): At 11th level, when fighting defensively or using Combat Expertise or total defense, a cad cannot be flanked except by a rogue or ninja whose level is four or more higher than the cad's fighter level. This ability replaces armor training 3.
Sweeping Prank (Ex): At 13th level, as a standard action, a cad can use a dirty trick maneuver against any two adjacent opponents that he can reach, making a separate combat maneuver check against each opponent. He must use the same dirty trick maneuver against each opponent.
At 17th level, the cad can use this ability as a full-round action to attempt a dirty trick maneuver against a number of enemies equal to 2 + his Dexterity bonus (if any). This ability replaces weapon training 3 and 4.
Treacherous Blow (Ex): At 15th level, when a cad confirms a critical hit, he can attempt a dirty trick combat maneuver as part of that attack as an immediate action. This ability replaces armor training 4.
Ultimate Payback (Ex): At 20th level, any critical threats a cad makes against an opponent that has attacked him since the beginning of his last turn are automatically confirmed. This ability replaces weapon mastery.

Con cualquiera de estos arquetipos y combinándolo con algunas dotes (había una dote en el Core que permitía usar cualquier cosa como arma; seguramente ya la tengas... y tampoco recuerdo su nombre xD), puedes sacar algo entretenido. Puede que tengas demasiado nivel como para ponerte alguno de estos arquetipos, porque ya tienes las habilidades que el arquetipo que te interese sustituye. Ten en cuenta, aún así, que hay dotes (en inglés) para reentrenar habilidades... Que viene a ser que cuando subes nivel, pagando X y echando X días (o semanas), varías cosas de tu personaje. Esas reglas están hechas para situaciones como esa... es decir, para poder coger un arquetipo que antes no sabías de su existencia pero que podría interesarte y venirle bien a tu PJ.
