Try that.

%%%%%%%
#(define ((myCallBack  number) grob)
(grob-interpret-markup grob
 (if (= (ly:grob-property grob 'direction) 1)
       (markup #:translate '(2 . 3) #:center-column (
           (#:fontsize 4 (number->string number))
           (#:stencil (ly:tie::print grob))))
       (markup #:translate '(2 . 3) #:center-column (
           (#:stencil (ly:tie::print grob))
           (#:fontsize 4 (number->string number)))))))


nineroll = \drummode {
\override  DrumVoice.Tie #'stencil = #(myCallBack 9)
sn4:32^~ sn
}
\new DrumVoice \nineroll

%%%%%%%%%
The drawback is that my knowledge is too low to find the right value for 
#:translate '(2 . 3) automatically.
(i didn't find any property of grob Tie that can help for that).
So this snippet has to be improved.
