This is in my opinion really interesting, and if doesn't get added I will do what
@jollow250 said and see if I can get it to work (just for fun).
We could have in the vanity menu, the villager skins, so we could switch between a bunch of different ones, just like when you select a hat.
The skins could also be inspired by the hats or skins from like you said, a famous person. ;)
And obviously if you want the default villager that is an option as well.
