Hi. Thanks for the suggestion. I'm currently trying to support a few modded planets (eg. Maraxsis, Cerys, and a few others.) and plan to expand the list. As I go I am looking for opportunities to have resources availability vary a bit more, as well. It's a bit tricky to balance with base Space Age, so I might eventually (not any time in the few months) add an advanced mode that spreads out resource availability more.
Once I get a bit farther in my updates, I might eventually add some planets, too, but not sure.
