Your creativity is astonishing! The big picture of all pieces together is amazing!
I personally would love to delete all my buildings and create a huge section-themed tourism instead... however this is practically impossible at later ages with very expensive technologies, FPs and goods, and sectors being harder and harder to acquire by fighting, even requiring some negotiation, leading back to the goods problem.
This question has probably been raised within your development crew but in any case it would be awesome to incentive cities to not be focused in production and battling, production and battling... I'm not sure how you could make this viable without having people exploiting small buildings paying tons of goods (which would be one of the big changes) but you're smarter than me.
With each event there usually is a problem for some eras - ether the prize fits End-game progress, Middle-Game progress or Early-Game progress. For example the Carnival event prizes really were not that much of help to small players. To see the point ask yourself if you were [specific] age player, what prize would you pursuit.
I think the set fits nicely for middle section, some IE, PE, ME. There are a lot of other prizes in chests, i`m in FE, unless all full set suddenly drops on me i won`t bother to pursuit it. I agree that in late game maximizing the city output is crucial, but IF it`s a full set, than it is worth having.
