New gamemode idea?

Wouldn't a gamemode thats basically a older patch be cool? like imagine playing season 1/2/3 again and its different everytime, like one time the gamemodes open its patch 4.13 and the next time its open its 2.6, etc.

I honestly think the only problem with this gamemode being out is that rift would have 5-10min queue times >.>

if theres anything else you think would make this gamemode idea better comment down below <3
