I'll tell you what it could be... If you slightly widened that lower structure under the saucer from port to starboard, you could call that the PF bay. That baby would make a BAD ASS pseudo fighter Tender! Feds dont have one, but that could be the ticket!~
I'm sure there is some template somewhere that would fit that ship in some sort of shirt and trousers. Have you tried any set of textures on her?
