New Game mode

So, I was thinking what if there was a game mode where all the champions that have been reworked , , etc, would be released like there old versions of theme selves and then they can have all of there old moves and that sort of stuff maybe if the old items. Now I know some champs got reworked because people just didn't like them or they were too old ,but there are the people who do want this kind of thing like me. It could be on classic summoners rift and we could have them free to play on that game mode if no one owned that certain champion so then everyone can have some fun and learn how they used to work/fight. I think this would be an amazing idea since we already have a good amount of reworks that happened maybe we could see what will happen.
