I hope my response didn't come across as an attack!

But my point was that a "normal" *chromatic* harmonica is tuned 
diatonically in a pattern generally called "solo" tuning, but with a 
mechanism to sharp and flat the notes.  It seems that any layout 
procuded by a generator for a diatonic harmonica could be applied to 
any instrument with that mechanism.  Solo, diminished, augmented 
wholetone, and any other tuning can be applied to the instrument 
regardless of any mechanisms for producing the "extra" notes.  

It would make sense to have layout generators that apply to the 
various mechanical bodies of harmonicas - dual chamber (w overbends), 
single chamber (w single reed bends), enabler-reed (XB40 style), 
slide mechanism (pushbutton style), etc., with their various numbers 
of holes/reeds.  Then the tunings are simply overlaid onto that and 
the extra notes are determined by the tuning and the mechanics.
