Idea for a random game mode

I am not sure if this has every been brought up or contempated by riot staff or previous discussios, but I think it would be interesting to have a game mode that goes back to a random patch. Like the game selects a random oatch in history, you still have 5 bans like a draft, and items, camps, objectives, champions, and other game systems are adjusted for said patch in this specific game. Like, it could go back to when dragon was just a gold objective, like season 3. Maps could change. Not sure if this is a possibility, but i could see interesting gameplay come out of it.
