New game mode idea!

I'm sure a million people have thought of this but what if there was a game mode where five to ten players spawned in random places on Summoners rift and it was every man for himself. Obviously queuing with friends wouldn't be allowed because they'd form an alliance and be total nuisances. But I think it would be cool. And there was no returning to base to heal and the shop could be accessed anywhere. And towers don't attack chapions ever! They're only worried about minions. And since its every man for himself there's obviously no real goal to reach except having the most kills :) And the game is over after fifteen minutes and players place instead of winning or losing :D and every time you chat it's technically /all chat! Basically king of the hill? I can answer any questions you have about my game mode! Thanks for reading!
