Lego Minifigures?

I don't know the cross over between Lego collectors and people who play LoL, but I'm sure we'd all agree that the introduction of Lego couldn't hurt.

Most champions I could see being in some of those blind bag type sets, each with their weapon and various small accessories. Then later down the line there could be a jumbo sized set for large champions or champions with large accessories; such as Malphite, Aurelion Sol, Illaoi, Rumble, Kled, Annie, etc. Then there are the skin variants.

And for big collectors, there could be a limited Summoner's Rift set, complete with towers, Nexuses, minions, jungle monsters, etc.
