I may be biased here by being a dedicated modder...
But isn't getting the mod done more important than the shipsets?

I mean, you can just grab a collection to stand in for your races from the hundreds to thousands of shipsets already made. People playing the mod on PBW are mostly going to be using their personal favorite shipset anyways.
On the other hand, there probably isn't a mod out there that even approximates the physics of your desired game universe well enough to stand in for it.
