I think the better approach would be loose the thing that is actually causing confusion rather than move it so it can cause confusion elsewhere in this context let me make that clear.

I am quite ruthless when it comes to things of this nature so you may as well loose that confusing shot entirely and use the opening shot from Return of the Jedi as has already been stated that Ady will have the executor arrive at DSII so is this shot not available?

In Adywan canon this may be the best solution all round

The Star destroyer going overhead minus the shuttle. perhaps even keep it makes no odds but obviously no DSII Endor could stay or be removed it would be interesting either way.

This shot of the bridge could then be used in ROTJ:R instead (As a Star Destroyer and in different context)... Like you say it is a fan edit.

Or as an alternate could be used for the opening of ESB have a Pan down to deep space then with the bridge shot then cut to the SD shots where it launches the probes this could be a real improvement in this context perhaps but it requires the footage being available from Jedi..... But there go my big clunky ideas again

Then there will also be no bones about what it is anymore...There is nothing wrong with the bridge footage everyone I think agrees, the context in which it is shown is the issue?

And it looks so much like a star destroyer bridge it could easily be used in the opening of ESB and not be confused for the executor?
