ScaryBob, I understand your issue, but I think you are confusing the point. What you are asking for is for stations to all share the same towers so that you only have one to aim at. This could be done with one centralized tower with massive transmitters, or could be done with many lower powered distributed towers.
The issue with one high power transmitter approach is the interference zone created is much larger. By having all the stations share several smaller towers within the city, the interference zone would be smaller, allowing better use of the spectrum (especially if a SFN is used).
Link to my TVFool results is in my profile Homepage URL. I suggest others do the same.
