I actually tried it and it didn't work.  I think implementing this  
approach in Scheme may be harder, as I would need to redefine \change  
(or catch for staff change events or something as hairy as that)  
rather than write a new function.

I will.  We have a good reason to want cross-staff chords rather than  
a fragile imitation that can only be held together by hacks involving  
negative padding :)
