New Short-Lived gametype idea

It is really less of a game type idea and more of a throwback. I am unaware of anyone else having thought of this and if I am not the first person to think of this I am sorry. Anyway I think it would be really cool if for a two-week game type there could be an option to play back on patch 1.1. I only started in season 2 and even then it didn't occur to me what was going on. I would like to play the roots of the game just to see what all the original champs were like and what not.
