somehow have to create more horizontal space for these manually.   


The following code tries to adjust this spacing automatically.   
But I haven't tested it with your font.   


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
#(define (markup-X-extent markup) (lambda (grob)
  (ly:stencil-extent (grob-interpret-markup grob markup) X)))

#(define (accidental-text markup) (lambda (grob)
  (modify-accidental grob 
    `((text . ,markup) 
      (X-extent . ,(markup-X-extent markup))))))

accidental =
#(define-music-function (parser location markup) (markup?)
 #{
   \once \override Accidental #'text = #$markup
   \once \override Accidental #'X-extent = #(markup-X-extent $markup)
 #})
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
