A good list Scott...
And I'd like to add to your list though, Fake Wedge...
The guy who chats it up with Luke, who was supposed to be Wedge, but who was replaced by Dennis Lawson. The guy sort of befriends LUke early, kind of a neat side character, doesn't really have a name I don't believe (unless you count him as Wedge already, which I don't).
Colin Higgins played the "Fake Wedge" as it were, and since they're two different guys, I'd really love to see him get a figure.
Mostly because he interacts with Luke in the briefing, and it sorta feels naked not having him to put into a briefing scene then.
Definitely agree on a rescuplt of Porkins... However, I think Biggs and Pops would be higher on my list of resculpting, personally. Pops never got a proper figure, and Biggs is a giant, while the actor's not terribly taller than Mark Hammil. I'd at least like to see the average-height body busted out for them.
Yavin has a few pilots I"d like to see done for the first time, and others redone or at least a new head on the average sized body.
