One big problem is the track width on the s550. It's huge compared to a gen 1. No way to get around that without custom control arms, custom driveshafts and serious modification to the rear subframe and the unit body on the gen 1. You'd be building so much custom, you might as well just start from scratch.
That's just the rear but, the front has the same problem, requiring massive modification to fit the entirely different suspension and engine cradle in.
Anything can be done, as has been said but, there is a point where it isn't cost-effective and requires mad skills most don't have.
