This method
 http://lsr.dsi.unimi.it/LSR/Item?id=784
is maybe more complicated than you need, because it takes trouble to 
distinguish C-sharp-up from D-natural-down.

You might need only the part with 
  \override KeySignature #'glyph-name-alist = \arrowGlyphs
and a simplified version of arrowGlyphs
  arrowGlyphs = #`(
        (1 . "accidentals.doublesharp")
        (3/4 . "accidentals.sharp.arrowup")
        (1/2 . "accidentals.sharp")
etc.
