Riot, please give champion summoner icons as a reward at the end of season (champion mastery reward)

For the champion you have the most mastery points with! this would be a nice reward considering the champ you have the most mastery points with is the one you like the most. Being rank 5 with the champ would be a condition of course. For example: The champ I have the most mastery points with is Cassiopeia and her rank is 5, which means I would get her icon (this one ) as a summoner icon for champ mastery reward.
