MvM in League?

Just as the title says Mechs vs Minions in League instead of a board game

How it works? Half the map, like nexus siege, but on the blue side. Minions will keep spawning, up to wave 30 or so. There will be more and more minions, getting more and more damage/health/resistance every wave. 5 Mechs. Tristana, Heimer, Ziggs, Rumble, Corki. Defend the nexus. Simple? Basically Coop vs AI but versus minions on the blue half of the map. Your team doesn't get minions, instead you can buy upgrades for your Mechs. Also, jungle monsters will be available. Summoner spells will be made into special abilities like Nexus siege. Whatcha think?
