Because of the curvature of the Earth, are nearby skyscrapers closer together at the base than they are at the top?

Yes.

If the two 100-floor buildings are one NYC block apart, which is 0.05 mile or 1/500000 of Earth's circumference, their 100th floors, which are .2 mile higher than their first floors, are going to be 2 * .2 mi * pi / 500000 further apart than their first floors, which comes out to .16 inches or 4 mm.
