Hi Urs,

as said before you'll need to go for the 'stencil.
Though, ly:hairpin::print, the default-stencil, is coded in C++. There
the defaults-heights for broken hairpins are set to 1/3 and 2/3 of
'height.
Thus we need a scheme-rewrite of the stencil-procedure to reset them.
Below I slightly extend a coding by David Nalesnik from
https://lists.gnu.org/archive/html/lilypond-user/2018-02/msg00181.html

Btw, the rest of the linked thread is very interesting as well:
Once you have a scheme-rewrite it's possible to add a plethora of
other features...

Back on topic.
Attached you'll find David's coding. My addition is to add a
'broken-heights-property.
Now you can adjust the values and call the scheme-stencil afterwards,
instead of the default-stencil.

Cheers,
  Harm
