Sory for my english...
This mod is a masterpiece. Atm i see that you are working on ship meshes and textures. I dont know do you make them on your own but if you do... i could have few ideas if you want to hear me. In game "nexus the jupiter incident" there was race of robots, called mechanoids:
image from google search[moa.omnimulti.com] are they easy to make?
You could also use some simple geometrics shapes like:

#3 from google[images.all-free-download.com]
#4 from google[static5.depositphotos.com]
#5 from google[previews.123rf.com]
#6 from google[st.depositphotos.com]
or some that are squre based:

I hope that i could explain my idea. That what i posted is not ready concept but i am just trying to show a direction.

Edit: when i asked about that mechanoid race i did not mean to copy & paste... I mean just to give some designe example... Personaly i would love to see ships // stations that are designed as 3d geometric abstract shapes, in your mod.
