I use special contexts for the highest and the lowest staff of each
group. It's ugly, but it works.

example:

\layout {
  \context {
    \Staff
    \type "Engraver_group"
    \name "StaffUp"
    \alias Staff
    \override VerticalAxisGroup #'minimum-Y-extent = #'(-3 . 5)
  }
  \context {
    \StaffUp
    \type "Engraver_group"
    \name "StaffDown"
    \alias Staff
    \override VerticalAxisGroup #'minimum-Y-extent = #'(-5 . 3)
  }
}

\score {
  \new StaffGroup <<
    \new StaffUp { }
    \new Staff { }
    \new Staff { }
    \new Staff { }
    \new StaffDown { }
  >>
  \new StaffGroup <<
    \new StaffUp { }
    \new StaffDown { }
  >>
  \new StaffGroup <<
    \new StaffUp { }
    \new Staff { }
    \new Staff { }
    \new Staff { }
    \new Staff { }
    \new StaffDown { }
  >>
}

Another option is to use an invisible empty context to create a spacer.

Cheers,
