New Game mode concept: Minion Apocalypse

Minion Apocalypse:

Either in Howling Abyss or Summoners Rift 10 players on one team, against a team of minions, a lot of minions, super minions, ranged minions, melee minions ever minion type, however, the 10 players on the one team don't have minions spawn.It starts off easy, but as time goes by more and more minions swarm, and it gets overwhelming. The object is to push to the enemy nexus. If the minions push to your nexus however,you lose. As for strategy, pick pusher champions who can clear waves quickly. This is just an idea that popped into my head, so I don't know whether it sounds good or terrible, so please give feedback!!
