IDEA - A League of Legends RPG App Game

I just got into Final Fantasy Record Keepers, and it is rather novel (if a bit of a grind). To put it simply, you put together parties of characters from the various FF games and send them into battle. You could have a party, say, of Lightning, Cecil, Sabin, and Bartz all at once! Coolies!

It also gave me this idea: What if there was an App game with similar gameplay, but you had League of Legends characters instead? Wouldn't that be kickass?

Besides, Riot wants to be known as Riot Games, not Riot Game. ;)
