I'm sure this is doable. Better still would be to create a few population centers of this density but slightly smaller. say 9 of them, 33x33. This would allow for redundancy of civilization (in case of disaster and whatnot). It also would allow better access to the appropriate resources (which is frequently a major motivator in which cities are successful). It still reduces the number of transport corridors, so trains an such become viable. The problem comes for people like me: I enjoy my small city experience. I live a short walk from downtown, but have a house w/ yard (and a big garden), and a garage/workshop (mostly workshop as I don't actually have a car). Such space uses are unrealistic as density goes up.
