restating clef and StaffGroup brace after \startStaff

[Gilberto Agostinho]

Hello,

Does anyone know if it would be possible to restate a staff's clef and a 
StaffGroup's brace after the \startStaff command? I am again trying to 
create a diagram showing non-consecutive measures side by side. I am 
able to set the bar numbers of these measures to arbitrary values as I 
wish, but I think the second measure would look better with clefs and 
braces similarly to the first. Does anyone have any ideas how to tackle 
this?

\version "2.19.82"
A = {
    \once \override Score.BarNumber.break-visibility = 
#end-of-line-invisible
    \set Score.currentBarNumber = #2
    \bar ""
    c'2 d'2

    \stopStaff
    s1
    \startStaff

    \once \override Score.BarNumber.break-visibility = 
#end-of-line-invisible
    \set Score.currentBarNumber = #13
    e'2 f'2
}
B = {
    c'1
    \stopStaff
    s1
    \startStaff
    c'1
}

\score{
    \new StaffGroup <<
        \new Staff \A
        \new Staff \B
    >>
    \layout{}
}
