Hide and seek gamemode idea

What if there was a gamemode where you had to disguise as a minion or a jungle camp or an epic monster or something and act like the ai as to not get killed? The other team would be regular champs and they could mess up and kill 3 things before being eliminated. And if they die while eliminating a disguised person, the disguised person wouldn't be eliminated. You never respawn, and you have 5 minutes before switching sides. It would probably be a boring ass game mode, but it might be fun.
