So if you want to do this, you're going to need to make some sacred hamburger.
1. You would need to remove the concept of spellcasting stats. Less hard than you think, since you could take the +0 - +5 you'd get from your ability mod and add it into the spell save/attack mod. You would completely divorce spellcasting from stat and allow for smart sorcerers, charismatic clerics and wise warlocks.
2. You'd likewise need to break the link between class features and ability scores. Things like ability score uses per day (replaced by proficiency per day) is a good start. You'd have to do something about unarmored defense as well.
3. You have to deemphasize physical scores to combat. Primarily, I'd get rid of Str/Dex to hit and AC. Leave Str adding to damage and Dex to initiative. Con can still add to HP. Make it so a fighter doesn't feel he needs sky high strength or Dex to be relevant and add to hit and AC bonus to level and class.
Otherwise, you're just going to create 300 micro features that say "swap x score for y" which is fiddly and only a bandaid. If the goal is for classes to be divorced from a specific ability score, it needs to be from ALL ability scores.
