No idea why alterBroken's not working, too late here to investigate.

Anyway, below may give you a starting point for a different coding:

      \override Hairpin.after-line-breaking =
      #(lambda (grob)
     (let* ((orig (ly:grob-original grob))
            (siblings (if (ly:grob? orig)
                          (ly:spanner-broken-into orig) '())))
       (if (and (pair? siblings) (equal? grob (car siblings)))
           (ly:grob-set-property! grob 'thickness 10))))

Cheers,
