I don't have the time to make a suggestion either,
but Joram's idea should be good.

I recently wrote that:

% Initialize first page number
pagenum = #3

% Enter a manual line break (for each pagebreak in the model)
% Increment the pagenum and label the instrument name with it
% (which should only affect the 'real' staff of the example score)
origBreak = #(define-music-function (parser location)
               ()
               (set! pagenum (+ 1 pagenum))
               #{ \break
                  \set Staff.shortInstrumentName = #(number->string
pagenum) #}
               )

This should be quite easy to adapt to barnumbers .
I didn't try this out but it should get you going anyway:

% Initialize bar number
barnum = #1

newBarline = #(define-music-function (parser location)
        ()
        (set! barnum (+ 1 barnum))
        #{ \bar "|" ; (or whatever you want)
         \set Score.currentBarNumber = #number->string barnum) #}
        )

Then you'll want to display all bar numbers.
