Yes, we have a feature request
(http://code.google.com/p/lilypond/issues/detail?id=2042 ), but no one
has done any work on it.

I suppose that the proper way would be to create new glyphs in our fonts
(using metafont, source file mf/feta-numbers.mf) and then adjust the
format-bass-figure function (in scm/translation-functions.scm) to use
those glyphs for the slashed figures.

You could of course try to modify format-bass-figure without touching
the fonts, but then it will always look like the figures in Robert
Kelly's table, where a + or a ` is stacked onto a normal digit, clearly
showing they are two different glyphs.

Cheers,
Reinhold
