I think for a tierce de picardie chord in the key of Gm, they would use a Natural to indicate the major third, and a Sharp to indicate the same interval in the key of Dm. However, that raises the important question of what an ABRSM Theory examiner would do, if I used a flat sign to write a minor triad in a chord where the major third is sharpened... Another think -- in the example you give, is a natural sign only there to "correct" a previous accidental on the figure? (otherwise, what else would it mean?).

What you call a "flat sign" would back then be called a "fa-sign" and the corresponing "sharp sign" would be read as a "mi sign". Both "voces" are independent of transposition, so "C♭" does _not_ denote a C flat (ces) but rather a C-fa which is exactly what is needed in your example in _both_ cases, so (in case this is not an original source) you might better write 65♭ in the first, untransposed case.

This is not soluble with the current input: changing accidentals would
require the engravers in FiguredBass to actually know what the base
pitch of the figure is, but that base pitch is typeset in a different
context not associated in any programmatic manner with FiguredBass.
So instead of writing 5+, one would need to be able to write something
like b<5+> (with b being the base note of the figure). And of course,
once one has all the information in a single \figuremode input anyway,
one would like to be able to engrave the baseline without having to
retype it (probably by having the engravers in Staff simply ignore any
figure information).

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...
