Sorry for double posting but I have to say If it could be done but It would probably be perhaps extremely difficult.

The Prequel trilogy done in a 70's sci-fi movie style. Not only would it grant a lot of artistic licence in terms of design but it could borrow a lot from this era.

Again with the sci-fi...

Star Wars is not sci-fi. It's fantasy, just set in space. And the Original Trilogy has been compared to have, in many ways, the style of a western.

For the PT to have a 70's sci-fi feel, or for the pursuit of/negotation for technological advancement to be a forefront part of Ep. 1's plot I think entirely misses mark on trying to make the PT feel like the OT does.
