I wonder if it's possible to re-engineer the Bezier curves used to build a font? The advantage of course would be scalability to any desired size without artifacts.

In programs like Photoshop or Illustrator any font can be converted to editable curves. If you mean "font" in terms of photographed analogue lettering, that's not easily possible, of course, especially at the low resolution the Star Wars openings are preserved in right now. From what I've seen of Mike Verta's scans though, his sources might indeed be good enough to rebuild a digital font out of those.
