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]
}
