An idea for a new mode

How about a survival mode where there is a team in a circled shape map void themed where you fight void monsters and after each wave there is a boss battle first with kha zix,then with kog maw,vel koz,rek sai and the final cho gath and the bosses would be at their normal size which would be huge.after each wave you could buy items at the shop and maybe if you die a teamate could revive you during a limited time or you would just be dead till the end of the wave.the bosses of course would be op and i generally think this mode should be fairly difficult so it wouldn't be that easy to beat and never play.anyway thats just and idea and opinios other suggestions would be really welcome
