Anything is possible if you have the cubic dollars needed to do it.
There are many ways to accomplish this, and many ways to successfully tune the car once done.
You can have any part you need fabbed if truly needed.
Personally I like FWD, because it presents a tuning "challenge" due to the inherent flaws.
This conversion would present a very large challenge, and I suggest you read every book on vehicle preparation, suspension, and engineering before you embark on such a challenge. Knowledge is crucial, unless you want to hand it to a big company and just let them do the work.... which is fine, but where is the fun in that?
