While agree with the others who are saying "it's silly, don't do it." I also tend to lean to an engineering side of things and I have an appreciation for the unique. With that being said, I suppose the easiest way to go about this would be to get your hands on the transfere case and differentials from the awd Ford Taurus. Then fabricate your driveshafts, make the electronics all work, because your speedo will more than likely need to be recalibrated, and then fire it up and take her for a spin. The car will gain a couple hundred pounds in the process, but in return, you'll have astounding grip. With a full bolt-on car and still probably weighing in at right around 3000 lbs, my guess is you'd have a sub-5 second 0-60 time.
But this is just looking at it from an engineering perspective. Costs could get driven up significantly with some of the custom fabrication.
