I think what was asked for was for the proportional spacing to be done based on
the stems position rather than the noteheads, with the result akin to this
horrible hack:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
up = { \change Staff = "up" \stemDown \temporary\override NoteColumn.X-offset =
#1 }
down = { \change Staff = "down" \stemUp \revert NoteColumn.X-offset }
\score {
\new PianoStaff <<
\new Staff = "up" {
\time 12/8
\clef bass
\new Voice { s1. }
}
\new Staff = "down" {
\override Beam.positions = #'( 6 . 6 )
\clef bass
\stemUp b8[ c' \up c' b]
\down b8[ \up c' b]
\down c'[ \up c']
\down b8 \up c' b
}
>>
\layout {
\context {
\Score
proportionalNotationDuration = #(ly:make-moment 1/12)
\override SpacingSpanner.uniform-stretching = ##t
}
}}
