It is *possible* to have optional arguments with default values:
http://lilypond.org/doc/v2.19/Documentation/extending/scheme-function-definitions
and http://lilypond.org/doc/v2.19/Documentation/extending/scheme-function-usage

Though in this case, a wrapper (like Urs suggested) is probably not a bad idea.
My scheme is a bit rusty (actually, it was never that good), but I'm
going to take a closer look at it as soon as I have time.
