I think that would probably work the best. Although it does feel like there is a missing 3PO line as they go up the ramp? Or is that how the original movie goes? I can’t remember.
His “Oh dear” could be shifted back a little bit to be at the same time that he starts flailing his arms around and I think it would feel more organic.
That’s the original. It’s a little awkward, but in fairness it matches his lines-to-arm-flailing-ratio in A New Hope, lol!
