There's a system very similar to your idea on the Dawngate closed beta. You choose a specific set of bonuses to get at the beginning of each game, much like how you would choose runes and masteries at the set of a League game. It hasn't been implemented in any sort of live server yet though. I like the ideas that you've put up.
