Yup, but you left out the ISSCV/APC - one of me faves
Reckon I could have some fun making missions with those...
Otherwise, you got em all bar the once-seen Chig shuttle thingy, not that that's an important one. The Chiggy mothership/carrier would be easy, since it's pretty much just a flattened octo-whatsit (you know, an eight-sided dude). The Teran carrier would be interesting, since the shape is pretty basic, allowing plenty of spare polys for turrets and missile launchers and what have you.
The Hammerhead would need to be ammended with fixed forward shooter (unless the source code boys have a suggestion), but the rear turret is easy enough. The ISSCV would need detachable pods, changing the basic shuttle from a cargo/passenger hauler to a gunship or APC, and allowing the recreation/thieving of the last episode
Model makers, I have one thing to say -
you know you want to...
