Hi Peter,

two possible methods:

(1) overriding BarLine glyph-name:

%%%%%% one %%%%%%%
musA = \relative c'' {
        c1
        \once \override Staff.BarLine #'glyph-name = #":"
        d
        \break
        e f
}

musB = \relative c' {
        c1 d
        e
        \once \override Score.SpanBar #'glyph-name = #"|"
        \once \override Staff.BarLine #'glyph-name = #":"
        f
}

\score {
        \new StaffGroup <<
        \new Staff
          \musA
        \new Staff
          \musB
        >>
}
%%%%%%% end of one %%%%%%

(2) moving "Timing_translator" and "Default_bar_line_engraver" from
Score- to Staff-level:

%%%%%%%% two %%%%%

musI = \relative c'' {
        c1
        \bar ":"
        d
        \break
        e f
        \break
        g a
        \bar ":|"
}

musII = \relative c' {
        c1 d
        e
        \bar ":"
        f
        g a
        \once \override Score.SpanBar #'glyph-name = #"|." \bar ":|"
}

\score {
        \new StaffGroup <<
        \new Staff
          \musI
        \new Staff
          \musII
        >>
        \layout {
          \context {
            \Score
            \remove "Timing_translator"
            \remove "Default_bar_line_engraver"
            \override SpanBar #'glyph-name = #"|"
          }
          \context {
            \Staff
            \consists "Timing_translator"
            \consists "Default_bar_line_engraver"
          }
        }
}
%%%%%%% end of two %%%%%%

Sometimes you have to
\override Score.SpanBar #'glyph-name = ...
in both cases.
