Call me crazy, but could this be, dare I say it, a 6-in-1? Maybe this is deviating from your ideal which might be to make 2 chapters to be viewed in a certain sequence, I’ve been grinding out my own prequel 3-in-1 and still finding it difficult to do any significant re-purposing due to lack of material, themes are abundant though and I love that you brought up Pulp Empire. I think you should follow that spirit, try to let each saga help the other. Many agree in the sequels Anakin is missing, with the prequels his story has a presence. Seems you can space out the scenes between each saga and have a lot more flexibility and leniency on missing details if it were combined. Just a thought.
