Well, I do not think the problem actually lies in the C++ code but in the way
I tried to override bar-glyph-alist - when I change the code in
scm/output-lib.scm, it does work... even with \bar ":||".

This solution works perfectly, thanks a lot! What I actually use is this code:
barCustom =
#(define-music-function (parser location one two) (string? string?)
#{
\once \override Score.BarLine #'break-visibility = #all-visible
\once \override Score.BarLine #'glyph-name = #(lambda(grob)
(if (not (= (ly:item-break-dir grob) RIGHT)) $one $two))
#})
and then e.g. \barCustom ":|" "||"
There is only one detail that need additional attention: It is not possbile to
change the bar lines at the beginning of the first line with this method. I
found the following workaround:
% start first line with repeat
\bar "|:"
% start first line with "thick" double lines
\bar ".|"
% start first line with "thin" double lines
\once \override Score.BarLine #'glyph-name = "||" \bar "|:"
Thanks again for finding a solution!
