Bringing things like All For One/Urf/Blood Moon, etc to custom modes.

I believe we should have the option to access old event modes such as Urf and All For One in customs, so we can play with friends 1v13v35v5 etc, I think it would really be cool to be able to access these modes whenever we wanted to, and i'm sure it would invite more players to come to league as well because instead of having to play norms, or wait for their favorite game mode to come back, they can just play it with friends in customs.

So who's with me?
