I'd like to suggest for more form and levels for palace, for both RFC and RFCE.
There could be 3 kinds of palace: Palace for agricultural and imperial, Chief horde for nomadic(like Mongol), and Capital for commerical and democratical/modern civs.
The originial, basic palace can only support up to 3 cities, beyond that there will be stability penalty. Upgrading palace can add stability, therefore we can encourage some capital moving.
This is a draft chart:
