\layout {
  \context {
    \Score \remove "Timing_translator"
    \remove "Default_bar_line_engraver"
    \remove "Repeat_acknowledge_engraver"
  }
  \context {
    \Staff \consists "Timing_translator"
    \consists "Default_bar_line_engraver"
    \consists "Repeat_acknowledge_engraver"
  }
}

But it seems like an astonishingly bad idea.
