Future champion abilities

Hey fellow league players,

me and a friend were thinking there should be a mage with elemental abilities and a random selection of those abilities while playing the game. let me explain, let's say has all of his normal abilities, but this while you are playing the game his passive aloud you to keep the base ability just with different effects based on the element. An example would be a stun, with fire you deal more damage, with water you take MR down, and with earth you lower the armor of the target. We thought about putting it on a champion concept but instead thought we should get feedback on our idea from the community.
