OK, full speed ahead!
So my 9,600 BTU/hr (minimum) would be a reasonable starting place for sizing the de-superheating heat exchanger.
If you start hunting heat exchangers on ebay, many of them are specified for water-to-water. So you'll need to find out what the refrigerant-to-water heat transfer rate will be... it will be substantially less, because water has an amazingly high ability to transfer heat. This means that the HXs will need to be bigger. You can find tables that specify refrigerant-to-water transfer rates this will make your task easier.
I don't know if you've ever worked with refrigeration, but I strongly advise you to start with something smaller, much smaller... to get your bearings. There are many air conditioners and de-humidifiers around, and you could hack one or two of them to get your tool set and skill set together before you hack into your home system.
Best of luck,
