Fun mirror mode idea

I know we had a mirror mode like game but the idea i had is the same 2 champs facing off against each other but one team must be a ap version of the same champ and can only purchase ap items. Could be done on the howling abyss or summoners rift. Im sure people would play this seeing that in ARAM alot of people try out ap or ad versions of champs anyways. So it basically boils down to ap versus ad.
