I've also made some custom wings, shields, and cargo bays, although it's hard to tell in the pics. I've tried to scale everything so that when the game generates an AI ship, it won't look strange.
The top two show one of my custom frames, and two of my wing sets. The bottom three show my military replacement frames.
I don't have names for them since they just replace the in game meshes. As you can tell, I like my ships to be VERY airplane-like (sue me, I like airplanes
Anyway, just thought I'd share.

I still need to fiddle with the UV mapping on them. Not entirely pleased so far.
For those of you who are interested, I did these in Blender. I exported them as an OBJ, then opened them in Lithunwrap. I then saved them as a direct X file with no compression and viola! Easy as cake.
