That’s a great backstory, however that’s not something I see happening in my edit.
In 1977, all of the backstory that people needed was that some rebels stole some plans. That was it. I don’t want viewers to have to read a few paragraphs of backstory before starting up the movie. I want all the viewer needs to know to be in the crawl, which would mention the Separatist Alliance, the Republic, and two Jedi rescuing the queen.
Also, 3PO and R2 contribute nothing to the plots of any of the movies. They are fan service for fan service’s sake (in my opinion)
The backstory in 1977 was the Clone Wars, the fall of the Jedi, the betrayal by Darth Vader, the murder of Luke’s dad. And a battle where secret plans were transmitted to Leia’s ship. There is a huge back story underpinning that simple tale. For the prequels (which mostly tell that story) you need a new back story. Who is Palpatine, what are these Sith and why do they want revenge? Why is the Republic falling to pieces? Why do the Federation want this particular planet (there are probably billions of them in the Star Wars galaxy)? The present springs from the past. You need a more compelling past for these films. And a more simple present. The droids aren’t just fan service. They are the Greek chorus. They need to be there but doing something that makes sense. IMHO
