I think you've hit the nail on the head here.
Looking at the screen shots in Paige's first post in the thread it appears the FC is indeed modular, consisting of a command section, an operations section and a flight deck section. It may be that the command section is dockable with either the flight deck or operations module or all three together. From those screen shots it is even possible that the capital class drive is also detachable and a separate module in itself.
There are some fun implications for this. Perhaps all the modules bar the capital class drive are capable of standard FSD jumps. Perhaps it's possible to own multiple operations sections and switch between them as needed. Imagine having 8 operations modules parked around your home station.
I'm starting to get giddy with the possibilities.
