There's no need for any Scheme programming at all. Just add another 
Bar_number_engraver to the bottom stave, that takes care of the bar line 
numbers within each line. Then you can also easily adjust the formatting 
fot eh two separately. Example:

\version "2.16.0"

violin = \relative c' {\repeat unfold 20 {c d e f | g f e d | }}
viola = \relative c'{\clef alto \repeat unfold 20 {g b c d | e d c b | }}
bass = \relative c {\clef bass \repeat unfold 20 {c2 e | g g, | }}

\score{
\new StaffGroup <<
\new Staff {\override Score.BarNumber #'font-size = #+3  \violin }
\new Staff \viola
\new Staff \with{
    \consists "Bar_number_engraver"
    \override BarNumber #'direction = #down
    \override BarNumber #'font-size = #0
    \override BarNumber #'break-visibility = #begin-of-line-invisible }
    \bass
>>
}
