You could use

  \context Staff = "ossia" \with {
    \override Clef #'stencil = ##f
    \override KeySignature #'stencil = ##f
    \override TimeSignature #'stencil = ##f
  } {
    \relative c' {
      c1
      \once \revert Staff.TimeSignature #'stencil
      \time 3/4
      c2.
      \once \revert Staff.TimeSignature #'stencil
      \time 2/4
      c2
    }
  }

instead of removing the engravers.
HTH.
