It could give a small boost while constructing culture buildings? Or an extra +culture boost in the capital?
You could have the opener be +2 culture in capital and border spreading, and then Ceremonial Rites be an extra +X culture in the capital and the free bulidings.
Another alternative which would change the policy; create a new dummy buildings "ceremonial rites" which gives +2 (3?) culture per turn and zero maintenance cost. Make it its own class of building "Rites" class. Have the Ceremonial Rites policy give a new building of class Rites in the first four cities you have.
That would accomplish a similar effect but without the timing issues and without the annoyance that the policy only gives you something you could otherwise build.
