"Vanilla" or Season 1-6 Summoner's Rift Mode

My idea is to have a Summoner's Rift throwback mode. Just as a new game mode to cycle like URF or Poroking etc. How fun would it be to play on the old Rift map or to see how the meta was and what jglers were used in Season 1? Or how the game's evolved from S1 to S3 and so on. Of course only champions that were actually released/available in that season should be available; along with the champions splash art and in game animations that were present then. All i'm saying is it'd be a fun thing to have for all the nostalgics out there who miss the times they had in S3 or S2 etc. Im not sure how easy this would be to actually make possible but I thought i'd just share with everybody my idea for a new game mode to cycle with the rest. If you have any thoughts feel free to post <3
