Hi,
you can try this:
By using the commands \stopStaff and \startStaff you can determine where
your staff stops and starts. You could also work with transpartent notes
instead of skips used bellow. Afterwards the bar numbers are corrected by
\set Score.currentBarNumber = #X.
(Used Version 2.8.2 on Windows system)
Let's have fun

\new Staff \relative c' {
c4 d e f g a b c
c, d e f g a b c
\stopStaff
s1 s1 s1 s1 s1
\bar ""
\break
\startStaff
\set Score.currentBarNumber = #5
c,4 d e f g a b c
c, d e f g a b c
c, d e f g a b c
}
