A thing I'd love to see would be a full length side-by-side comparison of ESB:R and an edit of the visually unaltered Blu-Ray like Adywan does in the brief comparison clips.
If Adywan didn't want to do this I'm sure someone would make one (I would for one) but a seemlessly synched version would be easier to render from the original source. A perfectly synched frame-by-frame version would be much more difficult for a third party to achieve.
I think it would be a fascinating viewing experience showcasing all the wonderful work on this project.
