Crazy idea time.
Vornado owns 2 Penn Plaza and the Hotel Pennsylvania. Demo 2 Penn (nobodies going to miss it, unlike the Hotel Penn), and dump the airights from the hotel, existing 2 Penn site, and MSG onto the 2 Penn site. I'm talking a single landmark tower with 6-8 msf of space. Easily 100+floors, maybe even 200fl. Potential WTB territory.
Preservationists get to keep the Hotel Penn, the Dolans get to keep the MSG, the city gets a new WTB.
