There are two versions
Right, but there are not 2 table entries to provide a Terran one for Terran Pilots and the Vasudan one for Vasudan Pilots. Which is a level of complexity (that while possible) that is annoying to have to deal with. That's what I was getting at.
As the only alteration is to the texture space in PCS, folks can feel free to substitute the model in favor for a cock pitted one if they so choose. But as for what was put in the MediaVPs (while it was a shame to do so, those are nice cockpits) at the time it wasn't felt to be a recommended solution to try and put both of them in.
This is, of course, not set in stone by any means. This is simply an outline of where and how the decision was made.
