I almost suggested one, but alas...they went too far and added tv series ships too. (A rotten stinking shame)
I acutally like the idea of being able to get my hands on all the Freelancer ships. There is probably a mod that does the Vanilla Freelancer ships, but I can't think of which one it is.
Personally, I've got the basics of adding ships pretty much down pat now.
All I have to do is go through the related files and make the necessary ini entries.
Those particular ships you're refering to simply require the type information that the player ships have in the shiparch.ini, then to be added into the goods and market ships ini's.
Simple, right? Not exactly..it's tedious and if you're not mindful of what you're doing, you'll end up with a lot of problems.

okay, okay...mod? Check out the mod download section. You might get lucky.
