Not very techy, at all, as for inserting “Skywalker” in it … is it possible or helpful to remove or voice over him with a “new voice” and says whatever he says, but the “new voice” then uses the “Skywalker” line whenever. I would think that may help it sound more natural than how he sounds and then a random “Skywalker” that doesn’t quite match it?
I wasn’t aware the alternative was even being considered, I don’t think that would work at all. Granted, we will have to check to see the audio channel situation but a full dub would definitely be more seamless.
