The correct way is to override BarNumber.break-visibility, preferable in layout:
\layout {
\context {
\Score
\override BarNumber.break-visibility = ##(#f #t #t)
}
}

Well, I didn't understand what you want instead.
Maybe play with
\set Timing.measureLength = #(ly:make-moment <whateverfraction>)
See NR for examples.
