you can actually make a regular barline to do what you want - just
need to do some engraver juggling:

\version "2.16.0"

\layout {
  \context {
    \Score
    \remove "Timing_translator"
    \remove "Default_bar_line_engraver"
  }
  \context {
    \Staff
    \consists "Timing_translator"
    \consists "Default_bar_line_engraver"
  }
}
<<
  { a a \bar ":" a a a a }
  { b b b b b b }
>>

i've found this by looking at some polymetric snippet in the docs.
