Accordion Stradella Chords

[TIM HUCKER]

Firstly & most importantly a big thankyou to everyone involved in Lilypond for 
such an amazing program - and free too! Please keep up the good work.

I am involved with engraving music for the accordion, particularly the piano 
accordion with stradella bass. As the actual notes that play when you depress a 
chord button are dictated by the instrument rather than the music, the notes 
printed are a matter of convention. 

For example, a chord of c major in the bass is conventionally represented as 
middle c with the g and e below it. On my instrument the notes that actually 
play are middle c with the e above and g below. 

Is is possible for me to redefine the chords in Lilypond so that I get the 
right inversion automatically, and the right chord name to go with it? I've 
tried any number of things and I just can't get it to work. Either the right 
chord come out with the wrong name or I can't get the right inversion at all.

Any pointers would be very gratefully received.
