League of Nostalgia

I think it would be cool to have a game mode option that allows players to play ~2009-2011 League, with the old items, old champions, and so forth. I'm aware this would probably significantly increase the amount of space that the game takes on a computer, but I think a lot of the playerbase would enjoy having a chance to relive their early League days, and it would give new players a chance to see how far the game has really come. The only problem is finding a good cutoff date where there's a variety of champions, but I think it would still be worth a shot. Thoughts?
