Unfortunately, this would be very difficult.  Elements are dumped into
the SVG file in the order they occur in the page stencil, and (almost)
every one is independently positioned as well.

Some of the related stencils are dumped consecutively (e.g. the
horizontal StaffSymbol lines), but I imagine this would require some
postprocess optimization, which is an interesting feature request.

I'll add this to the wiki.

I'm happy to be working on it, and I'm glad you appreciate it.

Thanks,
