cblakey1]Hmmm.. all these great suggestions and neither Clay or Comicbkguy has chimed in.
Okay, here are some general points to consider: I won't do Red Sonja because I don't do business with the owner of that license.
I can do my own Jungle Girl or Dinosaur Girl and probalby will. It doesn't make sense to license just a single piece of art from a 2-D artist unless the image really is amazing and the guy's name is Frazetta. I can design and sculpt my own, and plan to do so.
DC characters are done in house and working with them is doubtful. I think I would really only be interested in the Batman, but they know that. Nuff said on that.
