Game Mode: Definitely Not Summoners Rift

So I was thinking it would be so cool if riot made a game mode in which you were definitely not the champion you played... Picture this... You get in champ select now you click on but wait theres more you can click on another champion so you pick the game starts you load in as but when you get in game you have abilities no one knows accept your team... "oh look im laning against .... Oh wait WHAT THE *&%#@ He JUST SNIPED ME?!!?!?!".... I dont know i just feel like it would be really fun... PLZ Riot?
