Interesting. I've never been into this sort of thing, so I'm kind of wondering what the appeal is- this could also help explain why it's not explored as much.

On topic, though, there's an (old) issue of Superman where Lois Lane gets turned into a black woman so she can investigate the 'hood of Metropolis. He does it with a machine, and I don't know if there's a sequence because I haven't actually read the issue, someone showed it to me at Comic-con a few years back. There was a link once upon a time somewhere, but I think it was just a discussion.
