I agree. What about my idea of  not removing the Key_engraver and 
Accicental_engraver, putting it in the key of D major, and supressing the 
key signature with the line:

\override Score . KeySignature #'print-function = ##f

?

And also creating special note names for notes with flats like:

(bb . ,(ly:make-pitch 0 6 FLAT))
(Bb . ,(ly:make-pitch 1 6 FLAT))

?

Putting it in D major prevents the Accidental Engraver from putting 
accidentals in note in the key signature. Notes not in the key signature, 
like B flat would be printed. The key signature itself will not be printed 
if the key signature print funtion is set to false even if the Key Engraver 
is not removed.
