League Beta game mode

I had an idea for a temporary game mode. I think it would be really awesome to make a game mode where everything is identical to the beta version of League. The champions available (and their old abilities and stats), the graphics and animations, summoner's rift, the HUD, the items, and everything else. I personally would love to try League for what it was like way back in the day.

Even if not the Beta version, maybe the launch version? I don't know if Riot still has all the files for that stuff, but I would love to try that. Anyone else want to try this?
