Scorp, now you gotta make the rest of the cast of the Legacy comics. Cade Skywalker, Imperial Knights and many of the Sith characters would translate rather well in to LEGO form, I think.
I honestly don't know anything about those comics, but I have a particular customer who seems to be commissioning pretty much every character from them one by one, so you may just get your wish! I believe he's requesting Cade next, and another Sith character... I'll post them here when they're done!
