This is neat. Are you doing this with the deleted scenes as well, or just the theatrical movie?
Tbh I tried originally upscaling the deleted scenes using Topaz, but the results were very janky. And even still, there isn’t an HDR release of these deleted scenes to go along with this. It sucks cause I think the deleted scenes especially in ROTS make it 10x better and tie in neatly with Rogue One/Andor.
It is unfortunate that these deleted scenes were left out of the theatrical release. However, for your personal viewing pleasure, I would recommend the Bobson Dugnutt expanded edition that incorporates the upscaled deleted scenes in case you may be interested.

Good luck on this project.
