old champion versions (bring them back?) vs reworked versions

Hello all I still really miss the old Fiora. her game play was just to fun blade waltzing carefully so they don't cc you to death. i'm sure everyone has their favorites about their old version of the champions. Its been almost a year since the old fiora was removed . but i still like the new one, i'd just prefer the old Fiora then the new. so i was wondering if there can be a way to bring back the old versions of the champions in any shape or form such as or etc. and still keep the new version. In my opinion it be cool i think it would be cool to see the old Fiora vs the new Fiora or old Poppy vs new Poppy (blind pick not ranked) here are some ideas as to how i think they can be bring back the old champs.

1. Bring back some of the old abilities (1, 2, or even their whole kit) with a new champion.
2. toggle if you want the old or new one on the champions fan art.
3. or just make them completely separate the old vs the new. If this was to happen that would be awesome and thank you for taking time to read my idea
