If Starsky and Hutch can pull off a 70s look, why can't Stra Wars. It would be very cool IMO. The movies are set in a long time ago in a galaxy far far away. They are not set in the future. Why can't some things look a little outdated by our standards, while at the same time we have droids walking around and space travel is common place. I like the mix of old and new. For example, I had an idea for an animated series in which the Roman Empire never fell. The series is set in the future, so there would be robots and laser guns and stuff, but also people would still be wearing capes, and the soldiers would still resemble the old roman uniforms, etc. I think that would be cool.
P.S. Chrisdo, lay off the crack.
