I really couldn't agree more with the OP.
Remembering the mission briefings from Jane's USNF and other sims from the 90s made realize just how bare this feature is on FC2. More immersion in a future DCS title would be nice. If it is a Super Hornet game, I'd like to see flight deck crew doing their own thing instead of a ghost flight deck.
In Super VGA Harrier, they actually let you walk around the carrier (in a point and click fashion) and check for new missions, enter the com room and actually monitor missions that are already going on. Even visit the tower and watch other flights land and takeoff. I doubt you'll see that kind of immersion in a modern sim but it would be awesome to see.
