Bit hackish, but you could use:

\version "2.16.0"

omitParenthesizedBarNumbers =
\override Score.BarNumber #'after-line-breaking =
  #(lambda (grob)
    (let* ((text (ly:grob-property grob 'text))
           (text-arg (caadr text))
           (bracket? (string-contains text-arg "(")))
    (if bracket?
      (ly:grob-set-property! grob 'stencil #f)
      #f)))

\layout {
        \context {
                \Score
                \omitParenthesizedBarNumbers
        }
}

{
  \override Score.BarNumber #'break-visibility = #end-of-line-invisible
  \set Score.barNumberVisibility = #(every-nth-bar-number-visible 2)
  r1  r2  \bar "dashed" r r1 r r r r
}
