I'm a new (to me) pool owner and my pool is the same size as yours, and it has only one skimmer, but two returns, plus the one for the Polaris 180 cleaner. It seems to me that you will need to remove everything you have and use the skimmer opening only for a new conventional skimmer. Then plumb that back to the new location for the conventional pump and sand filter. A second return line would be better, on the opposite side of the pool and away from the skimmer. It's a can of worms for sure, so maybe a younger pool boy/girl would be better?![]()
