I thought about something like this a while back.
What if those summoner icons can be used to show your mastery of a certain champion? For example (these are just random numbers): 10 wins with a champion will let you have them as your summoner icon. 50 wins with a champion will let you have them as your icon with a bronze border. 100 wins a silver border, 150 wins a gold border, and 200 platinum.
