I do like the idea of the Voyager having a jump drive slot, given it's namesake - even a survey module would be nifty.
I'm not sure how I feel about a freighter being able to SNAC people.. However, I would support a freighter with a low core capacity/high regeneration rate so that it could lob Nova torpedoes at people. Alternatively, it would be nice to see a few freighters with a single bomber gun slot so as to mount Hellfire Rockets.
About the only thing I like about the Camara is that it lacks a CD so that I can summarily flee from solo Camaras. ;-; They're as bad as fighting a Pelican, if both pilots know how to turret steer.
Perhaps some freighters could keep their guns and be able to mount codename weaponry, whilst others replace their guns with turrets. Some freighters, like the Correo, feel a bit weak from only being able to fire 4 weapons backwards. Then again, perhaps some freighters are meant to be more offensive than defensive?
Further, I fully support the idea of more satellites/solars that only freighters could land on! Special commodities sold only on freighter docking points would be a plus as well - it gives the little guy something to be proud of from an in character sense.
