I tried something that seems to work, but it could require a lot of work 
for a score as big as yours.  It might be similar to your ghosting of a 
voice but it's hard for me to tell.

What I did was for a passage with whole-measure rests I created another 
voice with hidden notes, so that your "three" looks like this:

three = { \clef bass
  \repeat unfold 4 { a4 b c' d'} \break
  << { \oneVoice R1*3 R1  } \\ { \hideNotes c1*4 } >> \break
  R1*4 \break
  a1
}

The \oneVoice command keeps the rests on the right staffline, and using 
\hideNotes instead of skips keeps the staff alive.  If this works the 
way you want, then maybe there's a way to create some other function 
that will find passages with R1 in them and create an extra voice with 
the hidden notes.  That's beyond my ability though. :)
