I have made an Aires space station, and saved every single module, it may only be 7 pieces but it works. This Aires space station is similar to NASA’s Lunar Gateway, it is a space station that is to be assembled in Low Lunar Orbit for manned Lunar landings. These modules will be published individually so you can assemble it the way you want to, there will be a tug on every craft with plenty of mono and Delta V for your docking needs.
Cool! You seem like a pretty promising user! Hopefully you get a lot of upvotes lol! Good luck!
