I have a suggestion that you can take or leave at your leisure ...

How about presenting most/all of the deleted scenes in (very long) "flashback sequences" (akin to Julia :) ), as this would definitely give the whole movie a different spin and feel to proceedings.

In fact, to present Luke's longing to reach the stars as a past event would probably have more viceral (and 70s) impact than showing it in linear/real-time ... and given these scenes can be easily interpreted as a distant look back into Luke's life, rather than being intertwined within the concurrent timeline of the angst scenes with Uncle Owen & Aunt Beru ... as well as we only ever see that floppy hat of Luke's when he's whining to his friends or burning his eyes out through bifocals staring out at the dual suns etc.

Therefore, there may not be any need to "clean up" these deleted scenes, since the film scratches and reminiscing-B&W display will give more "authenticity" to Luke's recollection of happier days when he'd be playing with his Power Convertors from Toshi.

I only hope I'm not too late with this offering for you to consider this for maybe v3 of your edit.

Live Long and Prosper (and one hand up with a four-finger split arrangement that is not unlike a death-metal salute with extra digits). :)
