New gamemode idea (UPVOTE IF U LIKE)

So hi guys,

I have a great idea for a new gamemode i don't know if somone else got the idea before me orr not but my idea is: You will just have a normal champ select but when u get in game it all changes: -Every time you kill a person you will change into him with the same item and level and xp. I know its a stupid idea bqs when u are fed and u kill a low player you will not be fed anymore. But on my opinion it looks so fun and chaotic because you will have random sums on random champ.
