Love the idea of expanding the Western themed minis. Would add Mexicans to that list, as well as Asians, because those groups had a significant presence in that area.
A few pueblo style Kachina dancers
Great White Buffalo
You'd have to be careful about that. You'd want to make sure the Native Americans were accurately and not exploitatively represented. And I'm not sure that the Hopi are thrilled about the wide dissemination of Kachinas. I know for sure the Iroquois false face masks being displayed are a big no-no, but I'm not up on everyone's mythology and sensitive areas.
American buffalo / bison would be great, though. They would be awesome!
Consulting with an informed expert would yield information of which types of kachinas are considered sacred and should probably be avoided. But the kachina dancers are not unique to the Hopi. Many of the Pueblo indian cultures have masked dancers which play an important role in their religious ceremonies.
Yes! Steampunk contraptions!
There was a Mighty Mouse revival in the 1980s. It was genius. But televangelists shut it down for being too subversive for children. Ah, the 'eighties.
Mighty Mouse ( or am I so old nobody knows who that was??)
I had no idea Mighty Mouse was subversive. I just thought it was awesome...
But yes, super hero mousling.
