Could you use an "ossia" that overlaps the staff?

\version "2.19.82"

\new Staff = "main" {
  \clef "treble"
  c''8 g' a' g'

    \new Staff \with {
      \remove "Time_signature_engraver"
      alignAboveContext = #"main"

        #'((basic-distance . 0) (minimum-distance . 0)
           (padding . -10) (stretchability . 0))

Because of the non-standard positioning of the bass clef, I provided a 
version that uses an ottava bracket instead but keeps the note in the 
treble clef.  In both cases, I shrank the note size as in keeping with 
cue notes.
