One more idea (and I feel a bit bad for asking, since I dump the hard 
work on you again - not sure if I'm able to help):

W.r.t. the extenders to the second repeat alternative: spanners have the 
to-barline property that alleviates the need for manual length tweaks in 
such situations. Do you think it's possible with reasonable effort (in 
particular, reusing the code and/or strategy from spanners) to achieve 
the same effect for extenders? Such that, e.g., in your last example

\repeat volta 2 { b'4 b ~}
\alternative { { b b } { b \repeatTie c } } c4 c

\lyricsto "melody" { Here's a verse. "" "" }
\lyricsto "melody" { Here's \once \override LyricExtender.to-barline = 
##t one "" \earlyExtender #-6 more to sing }

would mean that the extender after "one" (that usually extends to the 
first note in the first alternative) would be stopped earlier, exactly 
at the barline? (Of course, in an ideal world, the "early extender" 
would have a corresponding from-barline property, but I don't think we 
have any example of such a functionality that we can rely on.)
