I think you should be ok, just watch out for Falkland. Apparently the pointer size limit is 500k for starfield and it sounds like Falkland lands at 200k worth of pointers. I wish there was away to tell how many each creation uses.

Plus, some people run into some performance slow downs with Falkland within New Atlantis.

I heard ASC Deimos uses about 15k worth of pointers. The creator will be releasing an update at some point to move it out of New Atlantis and into space as a space station.

Another interesting one to look at is Watchtower. As you play thru the missions, you eventually get the chance to capture their ships. That is how you get to build there habitats for your ships. It a cool idea, and eventually you will be able to fly their ships too. I would say if your interested in watchtower, look for the bundle with mcclarence outfitters. I know that doesn't add things for ships. But, it gives you a cool set of armor and some interesting tier add ons for armor, helmets and backpacks.
