If you want to avoid some of the jiggery pokery you could do something like:
%%%%%%%%%%%%%%%%%%%%
\version "2.25.12"
#(define ((time-alternate-time upa downa upb downb) grob)
(grob-interpret-markup grob
(markup #:override '(baseline-skip . 0) #:number
(#:line (
(#:center-column (upa downa))
(#:center-column (upb downb)))))))
global = {
\override Score.TimeSignature.stencil =
#(time-alternate-time "6" "8" "3" "4")
\time 6/8 s2.
\omit Score.TimeSignature
\repeat unfold 5 {
\time 3/4
\set Timing.beamExceptions = #'() %so 3/4 isn't beamed in whole measures
s2.
\time 6/8 s2.
}}
\score {
\new Staff <<
\global
{ \repeat unfold 66 a'8 }
>>
}
%%%%%%%%%%%%%%%%%%%%%%%%%
