No way to compare the slope of the fenders to a 968 without a field trip. But it seems to me those headlights are set kindof far back. and you'll note the accomodating shape to the fender from the bottom of the headlamp out to the nose that makes me think of an Alfa Spyder.
If we didn't have to worry about silly things like the wheel wells and the bits currently sitting between them and the existing headlight buckets, we might be able to locate fixed headlights far enough back to make them fit within the slope of the fenders. But if you're doing that much surgery there are other solutions...
