The way I eventually tried out the panoramic idea was with a (freshly serviced, "better than new") Pentacon-6 and the Arsat 30mm lens with 112 degree horizontal/vertical coverage, then cropping the neg to about 25x56. Admittedly the term 'panoramic' is not tightly defined, but this seems to fit the bill. One also gets a sort of pseudo rising-front if required, by moving the part used in the crop. Another strong positive point is that the negs print using common medium-format enlargers of course. There is some barrel distortion, as the Arsat is not a perfect rectilinear lens, so that must be considered when framing up your subject(s).
