Please elaborate?  It would be something like


 #{  \once \override BarLine #'break-glyph-function =
      #(lambda (gl dir)
        ..stuff..  )
     \bar ...
  #}

No. \bar should only create the barline specified. If you want special 
layout, then you should use a layout instruction, possibly hidden by a 
clever music function.
