There is the following layout for diatonic (extended meantone) system,  
which is what the Western musical notation system describes:
     A#  B#  Cx  Dx  Ex
   A   B   C#  D#  E#  Fx  Gx  Ax  Bx
     Bb  C   D   E   F#  G#  A#  B#
       Cb  Db  Eb  F   G   A   B   C'# D'#
         Dbb Ebb Fb  Gb  Ab  Bb  C'  D'  E'
Transposition is by translation in this diagram. So the same scale,  
interval or chord (disregarding inversions) will have the same pattern  
but translated. Different scale degrees are on different / diagonals.

I have used it for playing music in Scala and Chuck in various  
tunings, like Pythagorean and quarter-comma meantone (which sets the  
major second to the interval ratio 5/4). It works just fine.

It might be good for note input, as it does not impose E12 enharmonic  
equivalence.

But it may not be a LilyPond proper question - one needs an editor or  
key-map that can generate note names in LilyPond code.
