In 2.18, I use

barNrSffx = #(define-music-function (parser location sffx lastNr) (string?
number?)
 #{
  \override Score.BarNumber.before-line-breaking = #(lambda (grob)
   (let*
    ( (barNrTxt (caadr (ly:grob-property grob 'text)))
     (barNr  (string->number barNrTxt))
     (barNrStr (string-append barNrTxt sffx)) )
    (ly:grob-set-property! grob 'text (if (or (<= barNr lastNr)
                    (= lastNr 0) )
                 barNrStr
                 barNrTxt )) ) )
 #}
)

in use::
% music for mm1-16, for instance, then
\set Score.currentBarNumber = 1
\barNrSffx "bis"  16 % mm1-16 again with ornaments; bar number will read
"2bis", &c.
% m17 follows and will be numbered "17" (with no suffix)

Perhaps this gives you a start. I think the tricky part is using "caadr" to
find the current BarNumber.text so it can be reused. I'm sure many people
with better knowledge and skills can improve upon this...
