Pretty much: bass figure mode does not treat unsigneds lexically
differently.  It might be possible to do something like

  <\single\hide Bassfigure <6> 3>

in order to generate a music expression internally, but it would involve
several changes.

One is tweaking of chords by tweaking its internals instead.  I have a
change cooking for that.  The next would be unpacking chords from
function calls (and likely other Scheme expressions) when used inside of

And on top of that, this syntax is not particularly endearing with its
double wrap.
