A first idea:

\version "2.19.5"

my-with =
\with {
      \override BarNumber.break-visibility = ##(#t #t #f)
      \consists "Bar_number_engraver"
      \consists "Staff_collecting_engraver"
      \override BarNumber.after-line-breaking = ##f
    }

mI = \relative c' { \repeat unfold 16 { c4 d e f } }
mII = \relative c' { \repeat unfold 16 s1 }

\score {
  <<
    \new Staff { \transpose c cis \mI }
    \new Staff { \transpose c d \mI }
    \new StaffGroup = "mygroup" \my-with
    {
    <<
    \new Staff { \transpose c ees \mI }
    \new Staff { \transpose c e \mI }
    >>
  }
  >>

  \layout{
    \context {
      \Score
      \override BarNumber.break-visibility = ##(#t #t #t)
    }
    \context {
      \Staff
      \RemoveEmptyStaves
      \override VerticalAxisGroup.remove-first = ##t
    }
  }
}


Though, playing around with \mI and \mII you'll notice the BArNumbers
are not removed but overlay each other, while empty staves are
removed.
