An interesting idea about the clouds in ROTJ but there's a slight problem with that idea. We don't see Luke leave Dagobah and there isn't really a place where it could fit. Luke talks to Obi-Wan then we cut to the rebel fleet and the briefing then Luke appears. Adding a shot of Luke leaving in between that wouldn't really work

Hmmm...didn't think about that. I suppose it would be easy enough to compose a shot from existing footage but your right in saying it might not fit well there.
