I don't think you're approaching it from the wrong angle.
You need to get the springs & rods problem to express the
constraints you want.

I don't have the bandwidth to look into this right now, but
a good place to start would be the implementation of
ly:spanner::set-spacing-rods in lily/spanner.cc.

Yeah, it is one of those. Line breaking makes use of
knowledge about the horizontal spacing (there are more
measures per line if they are short, for example), so
those spacing constraints have to be accessed before
line breaking.
