You could do:

\defineBarLine "[" #'("" "[" "")
\defineBarLine "]" #'("]" "" "")

{
    \override Staff.BarLine.before-line-breaking =
    #(lambda (grob)
      (let ((glyph-name (ly:grob-property grob 'glyph-name)))
        (if (member glyph-name '("[" "]"))
            (begin
              (ly:grob-set-property! grob 'thick-thickness 1)
              (ly:grob-set-property! grob 'font-size -4)))))
    c' \bar "[" c' c' \bar "]" c'
    \repeat volta 2 c'1
    c'
    \bar "|."
}

Please shout, if further problems occuring.
There's still the possibility left to define a new bar-line from scratch.
