Hi Werner,

I've found no way to make it work.

Why not tackle the NoteColumn instead?

\version "2.19.15"

  \paper {
    indent = 0
    line-width = 50\mm
    ragged-right = #f
  }

  {
    c''1 ~ \break
    \once \override Score.NoteColumn.X-offset = 2 %% or whatever
    c''4 c'' c'' c''
  }

Cheers,
  Harm
