I doubt I would buy one, mainly because any two pianos are so different, and I don't think that whatever might be gained in cleaning up hiss, et al. would overcome what's lost in replacing the instrument that the pianist was in such intimate contact with with a different instrument and moving it all into a different acoustic environment.

The piano sound is one ingredient. But, this is not all we really love about Gould's Goldberg. If he happened to use a different piano, can you say his performances would be any less stellar?
Also, -apart from Gould- not all pianists are associated with a 'special' piano. Most of them played a variety of different pianos at different times, and in general if we happen to like the pianist, what piano he used during which session is only of secondary importance in general.
Don't get me wrong, I doubt if I'd buy any myself, but I can't help but think that this is only because of our prejudices and our preconceived notions about how this or that pianist is associated with an old sound.
Actually, if they made one for de Pachman I'd definitely go for it
