Jacques, does this help?
The code works for your example, but it would need a bit of work to generalise 
it.

\version "2.19.82"

whiteheads = #(define-music-function (music) (ly:music?)
  #{
    \temporary \override NoteHead.stencil = #ly:text-interface::print
    \temporary \override NoteHead.text = \markup {
      \musicglyph "noteheads.s1" }
    \omit \time 3/4
    \shiftDurations #1 #0 { #music }
    \omit \time 3/2
    \revert NoteHead.stencil
    \revert NoteHead.text
  #}
)

{ \clef bass 
  \key b \minor
  \time 3/2
  \relative { 
    d1. |
    e1. |
    \whiteheads {fis2 b,4 cis d b} |
    e1. |
    \whiteheads {fis2. gis4 ais2 |
    b2 b,4 cis d2 |
    e2. d4 cis2} |
}}
