Retro game mode

I have a new game mode idea for the RGM. What if we brought back all the champions un-reworked forms and jammed that into a game? For example, bring back Nunu, Akali, Aatrox, Irelia, Ezreal, etc. Maybe Akali could be that all-or-nothing champion, Aatrox can go back to attack speed and life steal, and full AP Ezreal with W as his main damage. What do you guys think?
