1. Copy the definition of format-bass-figure in a file and name it,
perhaps myDefs.ly
2. Rename the definition. Perhaps #(define-public
(custom-format-bass-figure figure event context)
3. Add your changes/additions.
4. Include myDefs.ly in the current file you're working on.
5. Call it with figuredBassFormatter = #custom-format-bass-figure (in
\layout) or with
    \set figuredBassFormatter = #custom-format-bass-figure in a context.

Isn't tested, but should work.

HTH,
