From what I can tell, the only reason this mod is incompatible with Space Exploration is that the SE post-process fix overwrites this mod's changes to labs (specifically, the adding of the tiberium research slot), preventing further research. But this could easily be circumvented/fixed by simply making a lab specifically for tiberium research rather than using the regular labs, so the addition of a tiberium research slot won't be overwritten by any mods that change research slots.

Yes, we could do that. But a) that adds pointless clutter and b) the same script would also wipe out our new lab.
The issue is specific to K2+SE>=0.6.65+Tiberium and will be fixed by SE updating their compatibility.

Fixed by space-exploration-postprocess update 0.6.18
