Modding Discussion Adding Dungeons/content to Asteroid fields/Astmosphere Biomes

I've been working on a total conversion mod for the past few months I've recently bought Tiled and have made a couple microdungeons. While looking in the folders it seems there is a map for a small mining facility that was supposed to spawn in the asteroid biome. I have attached the images, but this sparked an idea.

I want to add a couple different dungeons and enemies to the Asteroid field biomes and the space biomes above planets as they are very boring right now. I think they could be implemented using the airless dungeon script.

I'm wondering if anyone would have any suggestions in regarding to actuall get them to spawn in asteroid fields? Also dungeon ideas are always welcome. Also I want to make small spaceship enemies rarely spawn in these biomes and get rid of the skimbus spawns.

My current plans are:

Mining facility where you can refuel your ship

Abandoned mining facility

Research facilities

Space Stations both inhabited and uninhabited

Other ships, (i.e. Flagship cities, transport ships and of course crashed ships)

Bandit encampments
