Don't forget about Ion Cannon lady:

And to keep it on topic (not to mention that I did bring up another female that is in EMPIRE STRIKES BACK), is there any way to add a CGI overlay or whatnot to the AT-AT heads to give them more detail (or just more texture), being that the close-ups look very model-ly?

I figure nothing can be done (short of ILM and a few million pesos), but just wondering if ANYthing could be done to spice up the head shots...

Regardless, here is a 3-D AT-AT head (and body) someone created:

You should be able to "right-click" them for their full sized versions... looks to me that the only thing that is off is the "mini-gun" above the long lasers on the side turrets.
