What about the following trick? (It looks ugly on screen, but fine when printed)
It has to be adapted, of course.


%%%snippet

upp =
#(define-music-function (parser location note)   (ly:music?)
 #{ \once \override Voice.Accidental #'stencil =
          #ly:text-interface::print
        \once \override Voice.Accidental #'text =
          \markup {\musicglyph #"accidentals.sharp"
        \postscript #"gsave 0.17 setlinewidth -1.4 0.5 moveto -1.4 2 lineto
       stroke grestore
        gsave 0.1 setlinewidth -1.7 1.4 moveto -1.4 2.18 lineto -1.1 1.4 lineto
       stroke grestore"}
        $note #})

\relative {
        a b d \upp gis
}
