My question is this, could I use a water cooled heat exchanger as
opposed to the standard over-head fan air-cooled condenser?

These are made commercially and I know people who have them.

The principle is sound, but practically there are problems: 1. Corrosion of
the heat exchanger. 2. The hottest times of the year, your pool water is
also too warm alreadry (at least here in S Florida).

I've also seen them using pond water. Less corrosion then, but still a
problem.
