I was able to do a little bit of work on this tonight. I have a few AI Anakin lines to help with our 3PO retcon, but the setting of the Skywalker hovel does not at all lend itself to dialogue replacement.

The lines to mute would be, “Isn’t he great? He’s not finished yet.”
The replacement lines would be, “I’m fixing him up. He’s way better now!”

Not essential, as it works fine to simply skip over those lines.

Edit: Disregard; came back later and absolutely nailed it.
