This is a great idea for a mod. Disclaimer; I havent played your mod yet but check this out. You could have this mod bring the player to another playfield (lack of a better word) similar to how The Blueprint Lab mod works. Instead of the player pressing a button to go to a blueprint lab, you can make it so that the player pays a certain amount of fuel or something that then teleports them to a rounded map (simulating a ship travelling to a asteroid) instead of a square map like blueprint lab. The "asteroid" would then generate random resources just like the normal map yoyd be playing on but with an asteroid texture. This is very possible with your mod and you could use a large chunk of Blueprint Labs code to do it. Just an idea though, thanks for your submission, Ill check this out when I get home!
