Perhaps some economic modifiers for the Hanseatic League should go to the Mayors of the cities? A rich Hanseatic city should be able to grow more quickly than a random city elsewhere, even without the player spending money to upgrade it.
Perhaps a unique building that depends on the Hanseatic City modifier? Kontor's, perhaps, and they could give additional tax and galleys, and/or be used as an event condition.
