MvM in League?

i posted this in concepts/creations but nobody cared so...im sticking it here. anyways... 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. for the players... 5 Mechs, with upgrades. Tristana, Heimer, Ziggs, Rumble, Corki. Defend the nexus for all 30 waves and you win. Basically Coop vs AI but versus minions on the blue half of the map. Your team doesn't get minions btw Also, jungle monsters will be available, because buffs are great. Summoner spells will be made into special abilities like Nexus siege. Whatcha think?
