Now that Invisibility and Camouflage are a thing, can we get a "stealth on ally" effect?

I think it could be AWESOME to have a Champion who can put Camouflage on an allied Champion. Not Invisibility, as that'd be BROKEN on Champions like Malphite, Amumu, etc. But if you could help an allied ganker get into better position while still being detectable by the neo-pink wards, that'd be fair, right?
