Would it be easier to build higher buildings if they were shaped as pyramids or would it cause more problems due to the wind etc?

For example would it be possible to build a pyramid with the same apex as the Burj Khalifa (828 m.) or would it just be impossible for the base to sustain that much weight? If the money was there would we encounter more problems building such a pyramid than we would building normal "rectangular" buildings?

Not science disclaimer: This is not science.  
Land is sold by the acre which is surface area. The whole point behind very tall buildings like the Burj Khalifa is to maximize *that* patch of planet that it is built upon. When the design constraints begin at the very bottom, the only choice is to go up.  
Pyramids have very large footprints for buildings of their size. The Great Pyramids of Giza had no footprint constraints when design began. There is no reason that a pyramid would not be a good design for a very tall building. It just won't happen for a while because very tall buildings are only in demand in tightly packed metropolises.  
TL;DR: Location. Location. Location.
