As far as a new shuttle being used, I'd prefer the shortish shot of it's movement to still somewhat match what I think is a brief but terrific music cue. That's why the two shots above from 'JEDI' (if they are not to be used in 'JEDI') are too long in their overall full-length 'timing' to replace the original EMPIRE Stardestroyer it exits from. This would be a waste of the longer 'timing' of that 'JEDI' Stardestroyer element to my mind, when it could be say, accompanied by a longer 'Imperial March' cue over Hoth!....
If replaced, I wonder if the new shuttle will still come from the 'middle', larger bay (as shown in the top shot here from EMPIRE), or out of the 'front', smaller bay like in the two 'JEDI shots shown here?....like we tried to show in one of our examples, as shown in Monroville's post above.
