I've been experimenting with the concept of having multiple systems in single grid spaces.

It's tricky, but basically I can do it without crashing as long as I don't try to delete any of the systems in the space. If I do, I start getting errors and the editor becomes unstable.

The only problem is that you can only edit one of the systems in the space at any time. If you want to edit or even view the others, you have to move each system out one by one.

Unfortunately, it seems that having multiple systems in a single space is impractical. There is no way to choose any but the topmost system in the game, and thusly no way to manage your planets, ships, or anything else in the systems beneath the first one in the space. Plus it makes the editor and the game unstable with occasional errors cropping up. Perhaps it could be made into a practical concept with a mod?
