Was there ever a design for something like that for the Transit Terminal Tower , which I believe is ( in it's current design ) some 15 feet
taller than Wanda Vista . The whole idea of upper wind currents at those heights must have been discussed by someone ..... Right .

Hate to rain on your parade, but the 'Transit Terminal Tower' is still very much just a dream; its not part of phase 1, which takes the plans out well into the 2020's, so its extremely doubtful if any work is being done on that specific building. But if there is a developer who wants to build, I'm sure the time table would change. Its going to be a long wait before building over active train tracks makes sense.
The blow through floor is only needed because the building is so skinny. Buildings that are residents vs office building or hotels, are built so there's less movement. This isn't for safety but for comfort. Apparently someone working in an office is willing to put up with more building movement then someone paying big bucks to live up in the clouds.
