I don't agree much with most things in the OP and feel some those traits would be worse than the way traits currently are. Here's what I would do:
Spiritual - remove Cristo Redentor, remove Golden Ages granting no anarchy. Also remove Apostolic Palace but that's a given, every thread ever created about modding BtS should also begin with "remove Apostolic Palace but that's a given"
Creative - already good
Philosophical - already good
Financial - already good
Expansive - remove Worker production bonus, give cheap Aqueducts, or just +3

instead of +2
Aggressive - It's good, maybe add cheap stables
Protective - revise military and unit upkeep system. City Garrison promotion line grants free upkeep to certain types of units, other military becomes more expensive. Thus a real edge in standing armies for a protective civ - other civs can build archers/gunpowder units too of course, just becomes an advantage for them
Imperialistic - No settler bonus. Revise civics. State Property does not affect maintenance, can still affect corps, grants +1

to farms instead of workshop/watermill. Workshops also lose 1 hammer somewhere too, probably from Caste System. Imperialistic grants reduced maintenance from distance to palace. Representation loses +3

(move to +1

+1

for all specialists at Printing Press or similar) and grants reduced maintenance from # of cities.
Charismatic - it's good
Organized - it's good
Industrious - it's good
