That's actually quite a good idea. Based on your idea, the following should do 
the trick:

#(define my-alteration-glyph-name-alist
     '(
       ;; ordered for optimal performance.
       (0 . "")
       (-1/2 . "#")
       (1/2 . "b")

       ))

#(define (my-alteration->text-accidental-markup alteration)
  (make-smaller-markup
   (make-raise-markup
    (if (= alteration FLAT)
        0.3
        0.6)
    (make-text-markup
     (assoc-get alteration my-alteration-glyph-name-alist "")))))


My only problem is: How do I get this code to work, i.e. how do I get LilyPond 
to use this code in chord-mode? I assume I would need to somehow activate it 
in the ChordNames context, bit how does this actually work?
