What about the Maserati 250F, you could use a 2.5L Mas BiTurbo as a donor, lop the turbos off and fit a supercharger, and use the rest of the running gear.
I must admit when I saw the Vanwall at Goodwood, it didnt do much for me, I think it may have been watered down too much for road use, but still impressive.
