I'm pretty sure the modders have their own ideas. But as you can see, the the modeling part is the tricky part, not many guys doing that job.
I think the point of a good game is the system of it. Okay, it's better with new meshes and textures. But if just want to make new meshes, for the same game... you can't enjoy for a long time.
Or, if you make a new concept for the mod (gameplay, races, differences, ships, etc) and you open a new post for it, maybe new modders and old modders, too, will join the project.
