I love all these ideas, but a "trying to fall asleep thought" i had last night was this.
Could you puppet city states with culture? Similiar to diplomatic marriage.
Perhaps you can expend a social policy to puppet an allied city state. Instead of gaining a new social policy.
then the other half of the UA can be that each allied city state increases naval production by +5% and each puppeted city increases naval production by +10%. (Max 60%)
Then you could have the Boule UB that gains some kind of bonus from puppets. Then instead of gaining a free settler if you go down the Liberty path, you get a free Great Writer which you can expend for culture.

culture equal to your global
science output. Can expend Great Writers, Musicians and Writers to puppet or annex city states. (Can't build settlers)
production by +15% and +15 xp for naval units trained in this city. +3 city
defense and +30 hp.
