Well, there IS a Feat that does that. It's an Epic feat from the WotC websight. Lemme look it up...
Nifty, they have Epic Insights compiled into a nice little PDF!
Here it is:
COMBAT INSIGHT [EPIC]
Your keen intellect allows you to place melee attacks
where they will inflict the most damage.
Prerequisites: Int 19, Combat Expertise, Epic
Prowess, base attack bonus +15.
Benefit: When wielding a melee weapon, add
your Intelligence modifier rather than your Strength
modifier to the weapon’s damage rolls.
Appareantly its a very very Epic thing to do.
