...I may make a page listing the different types of Avatar minis, their canon origins, and all instances of each found in published missions. That way, people can view a relatively complete list of Avatar minis in case they want to adopt one.

Though that may have to wait until my next mission, which btw will concern AtLA/LoK, is finished and published. I've already found quite a few minis even though I'm still only 50% done...
