OK, this is what I have now.  I think it's a pretty good solution.

Looks good!

 

The code is capable of creating multiple cross-staff stems per moment.
It's possible to connect more than two stems as long as they lie on the
same line.  There is a workaround for a problem with Lilypond 2.14 that
has a flag as part of the stem.

I spent way too much time on the issue, but it helped me learn
Scheme and Lilypond.

That's ok; now that you're an expert, your next feature will be much easier... 

Cheers,
