BRILLIANT NEW IDEA FOR GAMEMODE!!!

Ok so we've had Black market Brawlers, Hexakill, PoroKing, URF, etc. Here is my idea for the next awesome game mode! Customize your champ! Basically you take abilities from all the champions and decide which ones YOU want to use in this mode! For example Diana's Passive, Nautilus's Q, Yi's W, Trynd's E, and Cho'gaths R. This is a rather simple idea, however, I do realize that this pretty much won't happen because of the complexity of the programming. I just thought I'd throw this idea out there anyways cause you never know! It would be the most fun, annoying, and hilarious thing to play and watch. SOOOOooo wish this would happen!

Edit: Just for fun post a funny or OP ability comp you would use! Kalista Passive, Fiora Q, Zed W, Yasuo E, and Ahri R. Mobility for days!
