Riot should implement a player "dodge-ball" style draft mode for custom games

I think the addition of a dodge-ball style summoner draft would make custom games much more appealing for LAN tournaments and large friend groups. The idea of having a large pool that players can join through the custom games tab and draft their friends like an old school game of kick ball or dodge ball would make a fun new twist on custom games, tournaments, and even All-Star games? thoughts?
