You don’t even need the \set Timing.measureLength, a \time command will
do the same when you set the TimeSignature.stencil to false:

\version "2.19.6"

#(define ((num-double-time-signature num1 den1 num2 den2) grob)
   (grob-interpret-markup grob
     (markup #:override '(baseline-skip . 0) #:number
       (#:line (
                (#:center-column (num1 den1))
                (#:center-column (num2 den2))
                )))))

#(define ((glyph-double-time-signature glyph num den) grob)
   (grob-interpret-markup grob
     (markup #:override '(baseline-skip . 0) #:number
       (#:line (
                (markup (#:musicglyph glyph))
                (#:center-column (num den))
                )))))

\relative c' {
  \override Staff.TimeSignature.stencil = ##f
  \once \override Staff.TimeSignature.stencil =
#(num-double-time-signature "4" "4" "6" "4")
  \time 4/4
  c4 d e f
  \time 6/4
  g f e f e d
  \time 4/4
  c d e d
  \once \override Staff.TimeSignature.stencil =
#(glyph-double-time-signature "timesig.C44" "6" "4")
  \time 4/4
  c4 d e f
  \time 6/4
  g f e f e d
  \time 4/4
  c d e f
}

This is my solution to a very similar problem in the German LilyPond
forum (www.lilypondforum.de/index.php?topic=1639.msg9143#msg9143)
