How about this?
They are both my own creations. I got the VF-1J blueprints from a Yamato toy, so the scales of the parts are actually acurate and correctly transform from Battaloid (robot) to fighter and such. The VAF-6 Alpha I found blueprints for as well, but they were hand drawn, and therefore actually needed some alterations to get the parts to all fit when in both a fighter and as a battaloid. Plus, I also modified them both a bit for personal tastes. I added horizontal stabilizers to the VF-1J because I never liked the fact they were missing on the original. The VAF-6 I made the feet a bit shorter. It always had some ridiculous clown shoes otherwise.
Getting it to transform in Orbiter, now that is another question. I think the best way would be some sort of swap out that instantly switches between two different ships in orbiter by pushing a button, perhaps even with an intermediate ship that you just quickly pass through in less than a second.
I think animating the change in Spacecraft DLL would be a major pain in the butt otherwise.
