Linking Intelligence to magic power is always going to be problematic since it either ends up nigh-useless for non-casters or way too good for casters. It would probably be better to distribute magic-related traits through several stats instead of loading them all onto a single one.
Constitution would work just fine as the "you can push more power through, so your spells are stronger" stat, for example; defense against magic could be handled by several things, if it even needs to be separate from nonmagical equivalents. (Does magical fire really need a different resistance mechanic than nonmagical fire?) Ranged spell targeting, if it comes up? Why not link it, like bows, to Perception and Dexterity instead of or along with Intelligence?
This assumes that the game wants to stick with "Strength, Dexterity, Intelligence, etc" as a feature, which it probably does. A case could be made for doing away with them in favor of directly dealing with the derived values, but it's probably too late in development to go that route.
