I’m intrigued to see which Ep4 scenes you plan to integrate. Some of them have potential.
For example the small moment in Ep4 where Leia takes Obi-Wan’s hand. Compare it to the Ep5 scene of them escaping Vader on Roken’s crowded ship and I see the faint chance that moment could be spliced together with the Ep5 escape, inserted before Roken sits down to talk to Kenobi. The discrepancies in the slightly too empty seats around them could maybe be obscured, but the only issue would be Obi-Wan’s slight costume change.
Anyways I’m happy to see that there are at least two projects being worked on for this series, and I can’t wait to watch your edit as well.
