Your Grace,
Gave it a go with CBP, no E&D, EUI (so moved those files as in the OP)
Couldn't see my dignitary count anywhere.
Something suspicious with the City View with CBP happiness but it was functional.
Magistrates Court etc had lower production costs than other buildings of their time.
I pushed a medium claim on a city state and it immediately (next turn) revolted due to loyalty

To upgrade my medium claim I needed 5 things but it only listed 4, not sure if this was time based or something?
Stopped after that, didn't see any colonies, but it was a standard map and I hadn't scouted what the Ai was up to.
The Claims stuff is pretty cool, and the integration with Cultural Diversity was nice! Love that mod. Not sure if the Loyalty stuff is taking it too far. I'm a bit of a minimalist when it comes to design and I'm not convinced it is necessary. I understand the idea of the Rhye's and fall style system of Player vs Game rather than Player vs AI, but I don't really enjoy that so much. That's just me. Making the claims thing work between players' cities, as I see you have been thinking in the options, is a cool idea though, and a nice way to bring that quite random ideology flipping under player control. That could be awesome.
Finally, I cried tears of joy at Leonardo's Workshop.
