I am, however, very much in favor of seeing a string of thousands of various cargo/construction crafts moving between the Death Star and the moon, which can include the Zeta-class; for there it makes sense and I hope we see it.
I was thinking of this too, but does the current dialog on the Star Destroyer allow for Tydirium to just be one of hundreds they’ve seen today? And would they all have to pass right over the Destroyer and “fly casual”?
It would be cool to see dozens of shuttles milling about the Death Star, but since the moon only contains the shield generator and this is operational, there shouldn’t be many craft traveling that way. So perhaps Tydirium is in a line of shuttles headed for the Death Star but breaks away for the moon, taking it across the path of the destroyer.
“Where is that shuttle going?” Could work!
But this would eliminate a very important piece of information, that Vader can feel Luke’s presence, and that he realizes that the Emperor was right, and his son came to him.
If he thinks this is just a rebel shuttle they might just shoot it down. I see no reason why Vader would let them land on Endor.
The only thing this changes is that Vader questions where the shuttle is going because it’s breaking from the normal route. It doesn’t alter the fact that Vader then senses Luke.
And they don’t think it’s a Rebel shuttle, it’s an Imperial cargo ship and the older clearance code they have “still checks out”. None of that is changed.
