I could possibly see a talent to let, say, and archer use intelligence, but there would probably have to be some kind of penalty of 30% damage penalty to bows (though intelligence would increase damage of bows as well, so with high enough intelligence it would counteract that penalty). There'd still be a certain advantage for a pure intelligence user over a hybrid, but not a gigantic one.
It still sounds like a huge can of worms even if it's a fun concept.
It would be FAR FAR better for the game to introduce "Hybrid" weapons to so speak.
So a intelligence based ranged weapon that works as a weapon for Archery skills.
It could be balanced simply by adjusting the weapon itself.
