I suppose if we go with this new 3PO line, there’s two other scenes that should be altered:

Before the podrace: “Oh, my, space travel sounds rather perilous. I can assure you they will never get me onto one of those dreadful starships.”
Note that any replacement for this line should have some sort of similar punch because right afterward we smash cut to the beginning of the podrace lineup.

Then, in AOTC: “I’m not worried, R2, it’s just that I’ve never flown before.”

I am certain TCW (and maybe Rebels) have ample dialogue to borrow for these two. But before I hurt myself roving aimlessly, anyone have any ideas?
