Gamemode Idea

So I was playing an aram the other day and had an idea for a game mode, that would be very different. We've had urf, and 1 for all but think of this one, aram style game mode where everytime you die, you respawn as a different champion of that class. So say you chose Marksman, started off as Ashe, but you died, instead of after death timer you respawning as Ashe you came back as Graves. Or tank, started as Mundo, and next respawn your Garen, another death and your Zac. It would be awesome youd have to build around the fact that you never knew what youd be playing next and what abilities, you wouldnt know what to counter either as the enemy champs would also be constantly changing. We have Tank, Marksman, Support, Mage, and Assasin, so in champ select people could chose one of these to play and be given a champ from that category to start. All random, every death, like a champion lottery, you never know who youll get next.
