You can create a slash directly, instead of hacking a Rest stencil:

slash =
#(define-music-function (parser location note) (ly:music?)
   "Make a beat slash with the same duration as note."
   (make-music 'PercentEvent
               'length (ly:music-length note)))

% Macro to print single slash
rs = {
  \slash s4
}

% Function to print a specified number of slashes
comp = #(define-music-function (parser location count) (integer?)
  #{
    \repeat unfold $count { \slash s4 }
  #})

Cheers,
