I was thinking the same thing Starfox said when I saw the nice mock-ups. Personally, I'd like to see "real SFC" data added into size/mass specs -i.e.; "warp," "impulse," and "aux" units add up to that ship's power, or phasers are listed as what types - "10 Phaser Mk 1, 4 Phaser Mk 3."
(As an aside, I still remember getting the FJ Tech Manual when it came out, how excited I was when I was 12, and then how I became disappointed in it by 13. The ships had a full page of names for each but next to no tech info on the ships, which was mostly the same "WF cruising, WF Emergency," etc. One of the things that drew me to SFB in '79 was tech stuff, even if it was game stuff like "turn mode" and "breakdown rating.")
Commentary on each ship sounds interesting too. Could be tactical, could be historical, could be anecdotal - "Flying the DNH against 3 Klink F5s once , and brole down on a HET early on! Got a few dents in my hull, but still took 'em all out. One tough motha."
And I'd love to help out however I can. Not sure this helps any, but I prepared this PDF for some additional ships I was adding for a campaign; it has the listings you might find on the ship in the Library section of the game, kinda what I was referring to above, FWIW.
