A counterweight doesn't change the speed at which something falls, does it?
It may reduce the apparent weight of the main structure, but objects of
different weights fall equally fast.

Counter-weight through a pulley or gear system?  A lessening • counter-weight

Your thinking of the "what falls faster, a tonne of lead or a tonne of feathers" question (or - "what's heavier, a tonne of lead or a tonne of feathers") which is actually more complicated than it seems.
