That’d be sublime at the script level. The scene where they reunite works without dialogue, but it could conceivably work as the scene fades
to black. It ought to be a low voice, almost a whisper. The music could be changed to accommodate, and the length of time spent in black adjusted (if not the length of the whole shot), if need be.

I love the idea, but as with any of these AI ideas, it will really depend how it happens to be able to come together.

Still waiting on the chance to try mixing the Luke line, by the way.
