There's so many champion ideas...

There's so many champion ideas that we know will never be accepted by Riot but are super cool anyway. What if Riot Games put together something at Comic-Con where everyone submits their champion ideas (art, lore, and all) for people to see. Of course, none would ever make it into the game, but it would be fun to see the "Unsung champions of Runeterra".

I know, cheesy idea with no writing whatsoever. Just a thought that popped into my head.
