Re: Instrument switching with a new staff - possible?

Good afternoon everyone,

I was attempting to engrave this piece today and I've hit a bit of a
roadblock.

Essentially what I'm supposed to do is have the piano break away from it's
"normal" grand staff for many measures (15+).

Then change to a percussion 1-line staff to notate the various percussion
instruments the performer must play as well.  Then return to standard piano
notation.

Is instrument switching possible in Lilypond, with a complete staff-type
change? I know you can add labels and change instruments, but I was unsure
it a total staff change was possible, temporarily, in a score.

I've done some experiments with instrument switching, but my code doesn't
seem to be working - only making things worse.

Could anyone possibly point me in the right direction please?  Thank you
kindly!

Note: I just used "dummy notes" in this example, for simplicity, so don't
worry much that the notes don't match :) That's not an issue.

My goal:
(something like this, but ideally the 1-line percussion part would be
centered in the grand staff, instead of up near the RH of the piano - but
that's flexible if need be)

My current code:

\version "2.17.10"

global = {
  \key c \major
  \numericTimeSignature
  \time 4/4
  \tempo "Slow"
}

right = \relative c'' {
  \global
  c4 d e f | R1 | R1 | c4 f g f

}

left = \relative c' {
  \global
   c,4 d e f | R1 | R1 | c4 f g f

}

This code more or less reproduces the image.

If a line break happens during a percussion part, maybe use "\clef percussion" plus an override to hide the clef change -- that way a percussion clef shows up at the line break instead of a treble clef.

I have no idea how to put the percussion clef between the other two. 

global = {

  \key c \major

  \numericTimeSignature

  \time 4/4

  \tempo "Slow"

}

right = \relative c'' {

  \global

  c4 d e f | R1 | R1 | c4 f g f

  \stopStaff

  \once \override Staff.BarLine #'bar-extent = #'(-2 . 2)

  \override Staff.StaffSymbol #'line-count = #1

  \set squashedPosition = #0

  \xNotesOn

  \startStaff

  c4 c4 c4 c4 | c4 c4 c4 c4 | c4 c4 c4 c4

  \stopStaff

  \revert Staff.StaffSymbol #'line-count

  \unset squashedPosition

  \xNotesOff

  \startStaff

  c4 d4 e4 f4 | g4 r4 r2

}

left = \relative c' {

  \global

  c,4 d e f | R1 | R1 | c4 f g f

  \stopStaff

  s1*3

  \startStaff

  c4 d4 e4 f4 | g4 r4 r2

}

\score {

  \new PianoStaff <<

    \new Staff \right

    \new Staff { \clef bass \left }

  >>

  \layout {

    \context {

      \Voice

      \consists "Pitch_squash_engraver"

    }

  }

}
