I could use the balance mod to create the map. That way there are lot's of choice planets to use for remote mining.
I would not mind allowing you to recolonize glassed homeworlds. I'm not sure the guy who glassed it would give you the chance though.
On the other hand I toyed with the idea of making it a mod game and removing colony tech, allowing you to fleet with bases, making remote mining not reduce planet value, and making the space yard component smaller, so you can get those remote bases setup sooner.
Stellar manip would be on, so you could use warp openers.
Creating a ringworld to use for remote mining? I'm not sure it's the most efficent way to generate resources, but if you can pull it off I'd allow it. And tip my hat to you.
