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)
