The problem with that idea is, some people don't play SR at all, just HA, so that would force them to play Rift games just to get mastery points on like the 6 champions they want to play.
What's so bad about being forced to play summoners rift. I think playing all the game modes (switching every now and then) helps bring versatility to gameplay.
Also if people think this is such a bad idea, maybe riot could add champion mastery xp to aram.
