Leugi or Sukritact are the only two I can think of who do ships...
I did do a couple of ships for my Future Worlds mod, although I think the surface ship I converted still has some flaws as I think the mesh gets deformed by the skeleton. The submarine converted pretty well, though -- probably because it's a fairly simple shape with few actual animations.
I'm not sure how hard the older ships would be to rig...
