Another issue is that Mexico City has a massive problem with air pollution and inversion layers. This will be one dingy, dirty, smelly hole in less than a year. You may be able to ventilate the interior spaces, (with sloped shafts?), but getting air movement in the "open" air? That will not be pleasant. Every third or fourth floor of the "glass facade", will be louvered "fresh air" intakes. I agree it is an interesting concept. But I also agree that the physical and engineering problems may prove insurmountable. Especially in this location.
