Hiya! So Lead handles itself with making metallic asteroids provide lead instead of iron by default, with an alternative crushing recipe. Though now you mention it, I can maybe iterate on that design with Crushing Industry. As for other brevven's other metal mods, I could add byproduct and triproduct results for them.
Creating new asteroid types for each type of metal would take a lot of time, increases the download size, and introduces balance issues, so I don't want to take that approach, but I'd be happy to explore more interesting solutions if there are specific softlocks issues. But Brevven seems to be tackling that himself as needed.
