A bad idea, but I went with it

I've installed Kivan first, then Adrian, together with the crossmod banters that come from the setup.

Issue: Adrian doesn't speak at all with Kivan. Is there any variable I could check to see if the "mod" is correctly installed? I feel like I should have probably use crossmod banter pack, rather than the component inside Adrian itself.

First Kivan mod then Adrian would be the correct instrall sequence. These banters are not in the Crossmod Banter Pak afaik.
The variable would be Global("G#XB.AdrianKivanBanter1","GLOBAL"). If it is "non existent" then it means it's 0, i.e. no banter happened yet.
NPC banter are randomly triggered by the engine. Make sure the NPCs in question can be seen (i.e. do not wear items that make them invisible or constantly hide in shadows).
You can test by pressing ctrl+i which increases "time" and usually triggers random banters, whether you can get the two to banter.
