Anything is possible with enough money and skill. This would require tons of research though. With out doing any research my self, I would think going with the V8 SHO platform may work. It would still be FWD and I'm sure there is a lot of modifications to do, but hey, I used to stuff 350 small blocks & 3800 SC V6's in the back of Pontiac Fiero's and still have a nice drivable (for a Fiero) car. All while looking like a factory install! Again, with the right research, money and knowledge anything is possible. I would suggest getting a plain jane Contour to do it on and upgrade the chassis and bodywork to suite. The only SVT parts you'll likly be keeping is the body work and interior so why waste a good one.
