old versions of reworks (possible gamemode maybe)

I think everyone can agree on one thing, they miss an old kit of a champion they used to play or just had fun on. sadly they can't have this fun anymore because this champion has been reworked because the champion overall wasn't fit anymore for the game or just couldn't be played. this resulted in riot reworking those champions, which I find a good thing. But my suggestion is that there is a (rotating) gamemode which is a 5v5 summoner's rift in which you get an old version of a random reworked champion. I think this could be interesting to both old and newer players to the game.
