Not sure how we could imply it, but I think it would be cool if we could explain that the reason the Sith Fleet needs to be controlled by some kind of tower is because all of those ships are completely empty, and they need to be remotely controlled. Maybe we could redub that dumb line about harvesting the galaxy’s young to man the fleet. How are babies gonna man the fleet you are launching in less than 16 hours? Maybe we could redub him to say, “We’ll need to install a comm tower onto this ship to control the fleet remotely.”
Certainly not the easiest way to go, but you might be able to change the long tracking shot looking out from inside one of the Exegol SDs as Rey is flying in to confront Palpatine. Grab a chunk of the second half (1:37:20 to end, say), preferably with the least amount of people in it, crop/mask out/avoid them as much as possible,
I wouldn’t want to try that, but there are some pretty talented folks on this board with way better skills & patience than me.
