A New Game Mode

Hello guys, I was thinking about making a discussion here ; I was looking for exciting ideas and I think I found one! Wouldn't it be great to have a gamemode for 1 or 2 weeks that allowed us to play league of legends as it was like in 2013? With the old champions, without any of the current reworks, runes, or the updated map! It would also have the old items. I know it doesn't sound that exciting but it would be SOOOOOO nostalgic for the OG's and would give the opportunity to new players to league to have a taste of the old days of this game.
