Most people only want human figures.
Plus Asians were not happy with these characters at all. They were up in arms, so I don’t see them ever coming out of Asia.
I like alien figures, especially non-humanoid. If they made them, I would probably get them. However that will never happen, aliens are harder to make, more expensive, non-standard parts.
it would make more sense to ask how many people would commission one of these, and see if enough people are interested to actually get them made by someone who does small runs.
