I don't really want to keep remarrying my wife just to see all the content. She might say no eventually, and then I'll feel silly.

Given that each character will see the new content 0-1 times in their life on average, I'm not sure this is a good use of resources given the cost of modelling all of those churches and choreographing all of those ceremonies. If they could make the facilities more useful outside of weddings too, so they wouldn't be ghost towns like the existing church already is, then it might be fun.
