Old School Champion Gamemode

I know this might sound odd but is there any chance that we could have a gamemode featuring champions before they were reworked. As a Season 3 Vet there are some champs that I would like to play again. I know it might not be possible but it is a thought that I would like input on. Also might be a fun random gamemode to add to the queue. Can I have everyone's thoughts on this. It might even be a fun idea to let the newer players try out the old champs. The only problem is that the champion pool would be limited and some items might not be available, but I think it would be an interesting concept.
