Hi badmotivator, I can address some of your suggestions here.
-Though cockpits are probably not going to be a part of the first release, they will eventually be included and will be based on what you see in the movies, though probably with some concessions made for the sake of gameplay.
-Although FSO's dynamic music system isn't as nuanced as I'd like it to be, it does provide for music that changes between combat and non-combat situations, as well as giving musical cues for ship arrivals and different mission outcomes. All of the music in FotG will be completely original in order to help us avoid getting shut down, though it borrows heavily in terms of style and instrumentation from the original trilogy soundtrack.
-Most of what you're talking about regarding squadron assignments can probably be achieved using FRED's advanced team loadout features and a thoughtfully laid out campaign.
-FSO already has a great power management system, which we are using, and it is customized on a ship-by-ship basis.
-While there's not really any framework I know of for something like talking to the Emperor's secret operative dude like in TIE fighter, debriefings (and the following briefings in the case of campaigns) can change based on your performance and be made to give you recommendations on how to improve on the things you did wrong.
-The cap ships will not be pushovers. If you take two fighters against a Star Destroyer, you will barely be able to scratch it, and it will most likely kill you at some point with a lucky turbolaser shot or two.
