I'd love to find some of that stuff myself... Closest I can think of is the Race Car Driver model Zygote has (had?) for sale... Though I thought there was a Rebel Pilot figure for download somewhere (it might not be poseable, and if it is, it might be one of the "Lost Models of Xanxost") - I think the uniforms Lucas used were modified racing suits, so these might work well, if they're still out there...
