Idea for a Rotating Gamemode!

Okay so i was thinking the other day, alot of onetricks and general players over the course of the years have been wanting to bring back old champion models/revert reworks or in general asking to play the old version of the champ.

I thought it would be cool to have the same type of idea as there is in nexus blitz where there is like a duel arena that you 2v2/1v1 or whatever in BUT, There's old champion models vs new champion models, so there's 5 champions being locked in in champ select and when you're ingame there's two 2v2's and one 1v1, all of those battle get to 2v2/1v1 with all 5 champs after eachother and one of the two can choose old champion model and one of the two gets new champion model, in the 1v1's they get to choose themselves. Team with the most points (gotten by winning 1v1's or 2v2's) gets the victory.
