Like that idea, still get the sentimental hit, but new as well. Obviously the sprawling city would need to be an important feature. Flying would need to be banned in the city ofc, as it would destroy that maze like aspect. City has grown taller over the centuries and gliding could be really cool. Why would flying have to be banned. If you like the map aspect, and want to travel through it on foot, then you have the option to not use mounts. Please don't let your preferences dictate how others should be able to enjoy the game.
