I did not read the whole post to see if someone has said this, but there is a mod for fighters in Pathfinder Chronicles: Campaign Setting.
It is on page 45, and reads:
Class Skills:
A fighter trained at a famous war college or fighting school gains the following class skills (in addition to the normal fighter class skills):
Diplomacy (Cha), Gather Information (Cha), Knowledge (architecture and engineering) (Int), Knowledge (geography) (Int), Knowledge (nobility and royalty) (Int), Sense Motive (Wis).
Skill Points at 1st Level:
(4 + Int modifier)×4.
Skill Points at Each Additional Level:
4 + Int modifier.
Class Abilities:
Numerous martial academies around the Inner Sea region teach weapon skill, tactics, diplomacy, and other tools useful for war. Fighters who attend these schools may choose the above option, which replaces the bonus feat gained upon taking the first level of fighter.
I personally think this is a fair trade -- excepting the weird x4 written into Skill Points at 1st Level. I hope that is a print error.
