I think what people mean by "unfreelancerish", is that some ships doesn't even look like ships... I've seen some hectice models on other mods, but then again, I've seen some very nice ideas for ships (...and no, I'm not talking about colour schemes, but designs).
Other than that, I agree with Dreygon - house factions should remain on one set of ship design (old or new), but Freelancers... well, exactly what freelancing means when it comes to ships...
Some house factions can even ban a certain ship (meaning 1 ship) from civilian usage... members only. That alone could solve a couple of already existing issues...:sleep:
