I have played around with idea's like this all the way back. (in WoD rules you add dex to hit on all rolls and str to damage) but what i find is better is more options.
All melee weapons are str or dex, and all ranged weapons are Dex or wis and AC is Dex or Int... always take what is better.
does having a high dex help for all of them still... yes, but it allows for a str/int melee class or a wis/int ranged one
