I highly doubt that could be done profitably. The water infrastructure support alone (increased water usage for showering, laundry, dishwashers) might kill it when you consider the sparse "office" kitchenette on every other floor and centralized shared restrooms (without showers) as they're currently designed. Then of course there's HVAC controls, external/internal wall insulation concerns, noise reduction issues, additional wear & tear on elevators through significantly higher usage... You get the idea.
