Switching Game Modes

I think it would be a wonderful thing if Riot would instill a way to change from blind pick to draft, dominion, aram, team builder, or ranked games from with in a lobby. For example say I'm in a lobby with 3 of my friends and were in a lobby for blind pick, but we decide we want to play aram. so instead of closing the lobby and restarting we could just switch it right from the lobby.

thoughts?
