There is a difference between Dungeon Fantasy, Fantasy and Realistic.
I would start with Realistic and add Fantasy to it in the form of so and so spells or powers can have this effect. Similar to Thaumatology Urban magics.
Think City Management from Pyramid given the full book treatment and covering a country or state.

However I think DF is geared towards something far simpler and would better be done as an article or How to use this in a DF campaign section of a more complicated book.
