Okay… I’ll make this happen.
At the same time, I think I’ll add a second style, matching the “canonical”
Orff format of num / notehead. As for the name, 'orff and 'note-fraction are my
first offers (in order of preference).
Thoughts?

I look forward to that discussion, and the subsequent code work!
Question (mostly from a design philosophy standpoint): What are the pros and
cons of adding a new 'style to TimeSignature versus just using something like
Harm’s “format-time-sig-with-note” callback [ed: Is that the correct term?]:
\version "2.19.83"
#(define (format-time-sig-with-note grob)
(let* ((frac (ly:grob-property grob 'fraction))
(num (if (pair? frac) (car frac) 4))
(den (if (pair? frac) (cdr frac) 4)))
(cond ((and (integer? (/ num 3))
(integer? (/ den 2)))
(grob-interpret-markup grob
(markup
#:override '(baseline-skip . 0.5)
#:column
(#:number (number->string (/ num 3))
#:override '(style . default)
#:note
(string-append (number->string (/ den 2)) ".")
DOWN))))
((and (integer? (/ num 2))
(integer? (/ den 2)))
(grob-interpret-markup grob
(markup
#:override '(baseline-skip . 0.5)
#:column
(#:number (number->string (/ num 2))
#:override '(style . default)
#:note
(number->string (/ den 2))
DOWN))))
(else (ly:time-signature::print grob))))
)
fancyTimeSig =
\override Staff.TimeSignature.stencil = #format-time-sig-with-note
\relative c' {
\once \fancyTimeSig
\time 9/4
\repeat unfold 9 c4
\time 3/4
\repeat unfold 3 c4
\bar"|."
}
Thanks,
Kieren.
