New game mode Idea

So I was looking at a lot of old champions and I thought of a cool and great idea for a new fun game mode that Riot could make. OLD Vs NEW This Idea puts up all the champions that have been reworked against the old versions of those champions, the select champion would work like how it is in all for one everyone voting to play a champion, one team is the reworked version of the champion and the other team is the old version. I think it would be a cool idea just to see the old versions of these champions come back for a special mode along with the deleted items that went away such as Deathfiregrasp. What do you guys think?
