If you read the Hara_kiri_engraver docs, it says

Like Axis_group_engraver, but make a hara-kiri spanner, and add
interesting items (ie. note heads, lyric syllables and normal rests)
Properties (read)
keepAliveInterfaces (list)
A list of symbols, signifying grob interfaces that are worth
keeping a staff with remove-empty set around for.

If that property were settable (on the fly), we could add
MultiMeasureRest to (or remove it from) the keepAliveInterfaces as
desired -- that would solve the problem!
I've tried messing around with keepAliveInterfaces, and this is quite pleasing:
\version "2.11.30"
show = { \set Staff.keepAliveInterfaces = #'(
rhythmic-grob-interface
multi-measure-rest-interface
lyric-interface
stanza-number-interface
percent-repeat-interface)
}
hide = \unset Staff.keepAliveInterfaces
\repeat unfold 4 { a1 b c' d' \break }
R1 \show R1 R1 \hide R1 \break
R1*4
}
two = { \override MultiMeasureRest #'color = #red
R1*4
R1 \show R1 R1 \hide R1
R1*4
R
R1 \show R1 R1 R1
R1*4
}
three = { \override MultiMeasureRest #'color = #blue
R1*4
R
R1 \show R1 R1 \hide R1
R1*4
R1 \show R1 R1 \hide R1
R1*4
}
\score {
\new StaffGroup <<
\context Staff = one \one
\context Staff = two \two
\context Staff = three \three
>>
\layout {
\context { \RemoveEmptyStaffContext }
}
}
The positioning of the overrides is critical (inside each system), otherwise they tend to interfere with the other staves.
