These are looking fantastic Black Wolf. So much potential with them too; Make the right modules to go with them and you can create practically anything! (loved Solatar's idea; never considered that)
My only worry would be that (assuming your using lots of individual components here) unless they're stealthed the poor player's radar is going to be a mess of blips. When you've finished the modules you wish to do, perhaps you could release them all together in a sort of "construction kit" DAE file? That way people that want big stations can mock up an arrangment with the seperate modules in FRED, and use the kit in a modeller to remake it as a single model. It's a pity we can't do some kind of "merge objects" thing, though i imagine the engine couldn't handle it.
But yeah, this is some truly amazing work here mate. They'll be invaluble to a lot of people that's for sure (definately got a ton of ideas in my head already).
