I'd ask Goa aboud 4X, and whoever did Infinite Space.
Sup. 
Hi I have a question, will infinite space and Enhanced 4X mod work together. I see that they both make changes to planets, will one simply override the others changes. If they don't work together can i take the unit scaling files form infinite space and put them into Enhanced 4X folder?
Well technically most of Infinite Space is already included in Enhanced 4X*, which is why both change the planets . The unit scaling is currently not officially supported however.
That said, if you delete the "GameInfo" folder in the "Infinite Space Scaled" mod, it *should* work with some certain oddities if you're willing to tolerate them. For example, it looks like the planet module placement areas will appear very big though the modules themselves will be properly scaled once laid down. But the actual scaling should still work.
Then just make sure to put "Infinite Space Scaled" above Enhanced 4X in your mod order and they should mostly play nice together.
*The actual planet balance is somewhat different, since I wanted the planets to feel more unique, but pretty much all the Infinite Space planet textures are in there somewhere.
