I mean I think it'd be cool. It could make progression slightly easier or harder depending on how its done. Of course it would have to have its own new system to do this. It could also open the door for several new items or features. Like new materials to build with. New block types to build onto your ship. New way to craft weapons/mining weapons. New way to craft subsystems. Potentially upgrade current turrets or current subsystems. The possibilities are endless. This was just what I could think of off the top of my head. Obviously it could come with its own issues in terms of balancing. But I mean, thats why you would test things out and make sure to get the communities opinion.
