    Wow.  Mahalo.
    
    I don't understand this yet but I very much appreciate your
    response.

Mahalo, X. I am using the naturalizeMusic function and will look into extending that.  Maybe that has some nuggets to mine.

\naturalizeMusic is not going to work well on \chordmode music (it will destroy the interval in chords, leading to wrong chord names), but you can use code like this instead:

\version "2.24.2"

enharmonization = { c cis d ees e f fis g gis a bes b }

converter = #(make-semitone->pitch (music-pitches enharmonization))

\layout {
  \set ChordNames.chordRootNamer =
    #(lambda (pitch lowercase)
       (note-name->markup (converter (ly:pitch-semitones pitch)) lowercase))
}

bflat = \chordmode { cis dis e fis gis a bis cis bes }

\transpose cis' a {
  \new ChordNames { \bflat  }
}

Best,

Jean
