but, as you can see, it's limited to one beam... :(

Any help from schemers ?

You could scale the stencil.  That way you wouldn't need to reconstruct the beam from what you find in 'beaming.  Of course this will only produce good results with flat beams!

 \version "2.19.15"

beamLength =

#(define-music-function (parser location myLength) (number?)

   (define (myBeamLength grob)

     (let* ((beam (ly:beam::print grob))

            (beam-extent-x (ly:stencil-extent beam X))

            (beam-length-x (interval-length beam-extent-x))

            (new (ly:stencil-scale beam (1+ (/ myLength 100)) 1)))

       new))

   

   #{

     \once\override Beam.stencil = #myBeamLength

   #})

\relative c' {

  \beamLength #10

  c8[c c c c c c c]

  \stemDown

  \beamLength #6

  c16[c c c c c c c c c c c c c c c]

  \override Staff.BarLine.bar-extent = #'(-7 . 2)

  \beamLength #3

  c32[ c c c c c c c c c c c c c c c c c c c c c c c c c c c c c c c]

}
