An idea for a new gamemode

I was thinking earlier on that we already have ARAM where we get random champs but I thought that it could be cool if we had a gamemode In which we get random abilities from every champ. QWER, Passive, and both summoner spells are random. So we could get a Heimerdinger with Garens passive, Luxs Q, Malphites W, Lee Sins E, Rivens R, Smite, Clarity.

I don't know what map this could be made on but I dont think it matters that much.

Please reply with your thoughts on this. Also if any RITO employees happen to see this please tell the team in charge of making gamemodes (if there is one) and if you are apart of that team .... then ... well.... Hi, i guess.

EDIT: It has been brought to my attention that some abilities would be useless if they didn't have other corresponding abilities (Jayce R). Obviously they wouldn't be allowed into the randomisation.

EDIT 2: Another issue has been brought to my attention. If it is truely random then people might not know what to build, i.e. AP or AD. A way to fix this is to have a 50/50 chance to get either AD or AP skills.
