The logic of the Span_bar_engraver does not appear catered to
independently running meters.  Basically, I would rather forego span
bars completely like ChoirStaff does.

But you can get by, in this particular case, with some manual
interaction:

\version "2.18.0"

one = \relative c' {
  \temporary\override StaffGroup.SpanBar.break-visibility = #all-invisible
  \time 3/4
  c2. c c c
  \revert StaffGroup.SpanBar.break-visibility
  \time 6/4
  c1.
}

two = \relative c' {
  \time 4/4
  c1 c c
  \time 6/4
  c1.
}

three = \relative c' {
  \time 3/4
  c2. c c c 
  \time 6/4
  c1.
}

\score {
  \relative c {
    \new StaffGroup <<
      \one
      \two
      \three
    >>
  }
  \layout {
    \context {
      \Score
      \remove "Timing_translator"
      \remove "Default_bar_line_engraver"
    }
    \context {
      \Staff
      \consists "Timing_translator"
      \consists "Default_bar_line_engraver"
    }
  }
}
