Sharp to flat transposition and rootless chords would still be one to one so the mech solution will work on them also. Sharp/flat consistency in rootless transpositions would be dependant on other chords in the tune.
The transpositions I'm not so sure about are double sharp/flats.
IMHO trying to transpose using anything more complicated, as described in earlier posts. is not worth the effort. The simple fact is we're already past that leval of detail, we 're using diatonic scales, the 'other' stuff has already been done. (Sorry Mike.
