I only rediscovered the line a few years ago. The designs are very barbaric and "dungeons and dragons." The armor and weapons have some great design details as well. (In fact, I'd actually prefer many of the GG designs to POP.) I was contemplating doing a custom MOTUC GG but didn't know if fans would even recognize her.
Yeah, it's a long shot to have them in classics but I for one would welcome them.
