The 70mm is an upscale anyway, so what's the point?
I think even if the original negative is 35mm, a 70mm print is still preferable to a 35mm print due to the size of the frame and the grain structure within.

Maybe, but I doubt the film size is going to be the most important factor. After all, you can only digitize to 4k Max either way (on most scanners), you're not going to digitize to a higher spec. When a film is as old as Star Wars the film has aged, it has faded, and developed many, many scratches and possibly warping. It'll need to be professionally cleaned first. You'll need a highly calibrated set-up to scan the film, you're going to scan in four channels for every frame one exposure at a time R, G, B, IR (for infrared correction).

Problem of course is that while technology gets better, the film stock gets older. If you had a print in your possession, it's going to take a lot of money to get it looking anything like the 2004 retail DVD. It can't be done by one person on a shoe-string budget.
