with that shot, you could change the slate to read "Blue Harvest" and it would not look out of place.
by the way, the photo gallery on the offical DVD said in a caption for a photo of the SSD Executor's bridge, said that they extensively re-created the set for Ep. III. The set where Admiral (soon to be Emperor) Piett scarred the bounty hunter Bossk for life ;P. I have heard that the Executor might be shown overseeing the construction of the Death Star. And will take place at about 19-20 BBY, not that long after AOTC.
