White diamond, black diamond, and possible small sponsorship?

[Trevor Bača]

Hi,

The black diamond shape notehead carries a different shape than the
white diamond harmonic notehead.

%%% BEGIN %%%

\version "2.11.7"

\layout { ragged-right = ##t }

\new Staff {
  \override NoteHead #'font-size = #3
  \once \override NoteHead #'style = #'harmonic
  c'4
  \once \set shapeNoteStyles = ##(mi mi mi mi mi mi mi)
  c'4
}

%%% END %%%


Does anyone know a way to get a black diamond notehead that carries
exactly the same shape as the white diamond harmonic (a "filled"
harmonic, in other words)?

I've poked around and don't believe this is currently possible.

If I'm correct and it is, in fact, not currently possible, would
anyone be interested in creating such a notehead? I'd be willing to
put a small bounty of some euros on it. (Seems like making this filled
harmonic glyph might be a fun side project for somebody who's been
looking for an excuse to dive in and modify the source, and therefore
might not distract Han-Wen, which is another bonus.)

If interested, please let me know ...
