Concept for a league of legends temporary mini game/variation

Had an idea for Riot to create one of those temporary mini games where all the ranks are ignored and you're put against any player. This way you can have bronze players versing plat players etc. I myself am in bronze and think it would be a great idea to improve skills in game by actually versing someone of a higher rank :D and im sure it would be fun for those who are already higher to carry and have a laugh at the silly mistakes bronze players can make. Would be so much fun!
