New Game Mode Idea

So recently I thought up a pretty cool game mode idea, I'm not sure how original this is but I think it would be super fun.

My idea is a 1v1 style game, only with 6 players all going against each other. It could work on a Dominion style circle map. There could be 6 shops/respawn bases, one for each player with a jungle in the middle as the main playing field. How you would win is to be the last standing. After a certain amount of kills (lets use 6 for example) you would be disqualified and watch as a spectator until the last player survives! I think it would be interesting to see how champs square up without a team to support them, and which match ups would have an effect on who ends up winning the game.

Please add any suggestions below, as I'd love to hear your feed back! Thanks!
