Is this mod compatible with the addon? Will it work on other planets?

It is not compatible, it is even marked incompatible in the dependencies.

Can it being compatible in future? I know thats break some separating, but anyway only one landing pad is available for planet. That's mean some challenge anyway

Not at the current state. I made some ugly workarounds because I was not sure how to do resource generation properly.

It would also be quite a bit of work figuring out what to do with all the planets, new resources, new recipes, new technologies and space platforms.
