Mastery Icons and Champion Spell Icons Please???

Wasn't 100% sure where to put this, but we've got champions, summoner spells, and item icons as well as the kinda emoji icons for brand, panth, jinx, and nunu. Although can we please get icons for the mastery talents or at least the keystones.

I can understand not wanting to do champion spell icons, because that's a lot of icons (640 assuming 5 per champion) to be saved in a cookie, and they change somewhat frequently.
