I've thought about it. There's no reason why it wouldn't work, the remote design has been used on cars with a similar or more cluttered underbody design with good success. The F body camaro comes to mind because of the transverse muffler and the severe lack of space anywhere under the car.
IMHO I think this design could be the easiest and most cost effective way of turbocharging an SVX if somebody made a kit. You don't have to deal with running hot pipes around your engine bay, or trying to find a space just big enough to mount the turbo.
Also, I'm guessing most people that bring up the issue of lag due to the extra piping have never ridden in a car that has one
