Rotating Game Mode Suggestions

Hey, I have been playing league of legends for a while now, and have noticed that I have been playing much more special game mode or ARAM instead of the normal Summoner's rift 5v5. I tried to find a discussion made of people pitching ideas for new game modes because frankly some of them are less appealing than others. Since I didnt seem to find one that seemed recent, I figured I might as well start one.

Here's my idea, a game mode (maybe Summoner's Rift 5v5 or ARAM) where you start with a random champion, and every time you die, you spawn with another random champion, with fully refunded items. ARAM might work better because you die more.

I feel like there are plenty of creative and fun ideas for new game modes and some might be good enough for riot to notice. Share your thoughts!
