Use ly:item-break-dir to find out where the bar number is, then set
font-size based on its direction:

\version "2.13.36"

\paper { ragged-right = ##t }

\relative c' {
  \set Score.barNumberVisibility = #all-bar-numbers-visible
  \override Score.BarNumber #'break-visibility = #end-of-line-invisible
  \override Score.BarNumber #'stencil =
  #(lambda (grob)
     (let ((break-dir (ly:item-break-dir grob)))
       (set! (ly:grob-property grob 'font-size)
             (if (= break-dir RIGHT)
                 -2
                 -4))
       (ly:text-interface::print grob)))

  \bar ""
  c1 | c1 \break
  c1 | c1
}

Cheers,
