Further to my comments earlier about the briefing, it might make sense to have some of the attendees by holograms (the fleet is big and presumably some of the people needing to be briefed would be also needed on their ships at the same time).

It might be easier to put Doddona Kebab etc in as holograms than to stitch their heads onto other actors bodies (it looked very fake in the PT).

The holotable might be able to project out as well as up so act as the holographic hub for the whole meeting.

There are also some astrodroids around which could project some extra characters in.

It might also be nice to have some ANH style Alderaanian troops around (the end celebrations seemed to make out that they were not specifically Alderaanian uniforms and it would be a nice continuity nod).

I hate the Rebel General outfits but I can't see there being anything that can be done about those.

Anybody want to give this a go as I'm a bit rushed off my feet at the mo (I did manage to tinker a bit with my previous mockup if you flick back a page but it still looks a bit crap).

Are these the blockade runner dudes with the vests and big helmets?

I would say yes as I always liked those dudes, but RotJ is like one big continuity nod. We see almost everything from the previous films thrown up on screen.
