Instrument switching with a new staff - possible?

[SoundsFromSound]

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
  
}
