There were some wheels made by Accucraft for their AMS line with hugely conical profiles, whether it was to enhance the differential action of a larger diameter contact on curves, or to enhance the self centering ability on track, they were a phenomenal failure. They were removed from further production cars, but still sold to the market as replacement parts...
As everyone above has pointed out, there is a fine line between too much taper and not enough, and it can indeed be speed dependent.
Most people have come back to 2-3% taper, and a "reasonable" fillet between flange and tread, but with our unprototypically tight curves, there is no great solution other than having one or more wheels turn independently of the other.
