Just an extra thought: when you do any 'optimizing' of ship models, how about adding a few more for some of the empires/races to flesh out the selection? If we had a couple more Fed ships it would then be possible for someone who doesn't have ship modeling skills make a nice Trek campaign using material from your mod.
A decent 'destroyer' class vessel like the Saladin/Hermes single nacelle design, and a 'heavy' class like the Nebula or Galaxy would make the Federation ships complete enough to use in a full campaign of some sort. The Miranda (USS Reliant from Wrath of Khan) would be very cool to have, as well. And maybe the Akira class. Various science vessels could wait for a full-scale dedicated Federation mod. Oh, a Fed-style
starbase is also needed.
The Klingons need at least one 'heavy' ship. The K'Vort might be a good choice. And a unique starbase design for them, also. And I see you've got
one Romulan model even though they don't appear in this campaign. The original Romulan 'Warbird' would be really, really cool to have and then of course a unique Romulan starbase. Hmm. Seven or eight models. Got any helpers with all of this?
The Millenium Falcon as a Rebel freighter would be very nice.
The Imperial Super Star Destroyer is out of bounds, though. It'd take up half a system all by itself!
