\harmonicBy... is defined in ly/music-functions-init.ly; based on this 
definition, something like

mixedHarmonicByFret = #(define-music-function (parser location fret 
music) (number? ly:music?)
   (_i "Convert @var{music} into mixed harmonics; the resulting notes 
resemble
harmonics played on a fretted instrument by touching the strings above 
@var{fret
}.")
   (let* ((fret (number->string fret))
          (pitch (fret->pitch fret)))
         (make-sequential-music
          (list
           #{
             \override TabNoteHead #'stencil = 
#(tab-note-head::print-custom-fret-label fret)
             \override NoteHead #'style = #'harmonic-mixed
           #}
           (make-harmonic
             (calc-harmonic-pitch pitch music))
           #{
             \revert TabNoteHead #'stencil
           #}))))

should do the job, but I didn't test this.

HTH,

Marc
