All Random Summoners Rift

I would like to propose a game mode that like the ARAM, can be a distraction from draft play and diversify summoner's champion pools . The problem with an all random Summoners Rift would obviously be the inevitable fighting over lanes. This could be solved by locking the fountain in the same manner as Dominion, assigning each summoner a random lane with it's own random pool of champions unique to his or her role, allowing a specified time to buy items, then teleporting summoners directly to lane with some time to set up leashes and other pre-minion shenanigans (Jungler would get a mid turret TP). I'm not sure if it's practical, but I'd play it. Tell me what you think. Or better yet, just get to the drawing board.
