This is an interesting problem and I suspect it would need some coding
(Scheme?). As you probably know, docuentation says:
"Although the support for figured bass may superficially resemble chord
support, it is much simpler. \figuremode mode simply stores the figures and
the FiguredBass context prints them as entered. There is no conversion to
pitches."
I wonder whether you or someone could write a new engraver for chords
"FiguredChordsEngraver" so you would enter them as per
http://lilypond.org/doc/v2.18/Documentation/notation/guitar
and see figured bass output...
