You are going to have to chase out the wall and fit 3/4" back plate elbows and you will have to maintain the standard family air gap plus install check valves and iso valves aswell. A job for a very good DIY'er or the pro's really. If you do not know what you are doing you could contaminate you're drinking water and get into all sorts of trouble with the water board.
