Doesn't work too :( it says

mf2pt1: command not found

But since
  mf '\mode:=proof; input feta-noteheads20'
  gftodvi feta-noteheads20.2602gf
worked, then i suppose we can live with that?
Or would it provide some important information?

aha. I'll look into it when i have some more time. Thanks :)

That's a surprise. It works :)
And you know what? The spikes are gone! :D

Unfortunately the downstem flags turned out to be more tricky to
change than upstem ones. This means i'll have to dig deeper into
metafont, and it will take an unspecified amount of time since i'm
getting more busy now.
I'll let you know about my progress this weekend (or hopefully earlier).
As for now i attach the first draft of output. Clearly it needs some work.

You can compare it to the current behaviour by compiling this:

\paper { ragged-right = ##t }

\relative e'' {
  \autoBeamOff
  \voiceOne
  \cadenzaOn
  c8.[ g16] b[ e] \bar"" \break
  \scaleDurations #'(1 . 8) { g,4 a b c d e f g } \bar"" \break
  \scaleDurations #'(1 . 4) { g,8 a b c d e f g } \bar"" \break
  \scaleDurations #'(1 . 2) { g,16 a b c d e f g } \bar"" \break
  \scaleDurations #'(1 . 1) { g,32 a b c d e f g } \bar"" \break
  \scaleDurations #'(2 . 1) { g,64 a b c d e f g } \bar"" \break
  \scaleDurations #'(4 . 1) { g,128 a b c d e f g } \bar"" \break
  \voiceTwo
  \scaleDurations #'(1 . 8) { d4 c b a g f e d } \bar"" \break
  \scaleDurations #'(1 . 4) { d'8 c b a g f e d } \bar"" \break
  \scaleDurations #'(1 . 2) { d'16 c b a g f e d } \bar"" \break
  \scaleDurations #'(1 . 1) { d'32 c b a g f e d } \bar"" \break
  \scaleDurations #'(2 . 1) { d'64 c b a g f e d } \bar"" \break
  \scaleDurations #'(4 . 1) { d'128 c b a g f e d } \bar"" \break
  \cadenzaOff
}

Thanks for all your help!
