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

(#: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 }

}
%%%%%%%%%%%%%%%%%%%%%%%%%
... and without any new insight, but with a healthy dose of syntactic sugar:
\version "2.25.9"
#(define-markup-command (timeSignature layout props fraction) (fraction?)
(interpret-markup layout props
(markup #:override '(baseline-skip . 0)
#:number
#:center-column ((number->string (car
fraction))
(number->string (cdr
fraction))))))
alternateTime =
#(define-music-function (one two) (fraction? fraction?)
#{
\once \override Timing.TimeSignature.stencil =
#ly:text-interface::print
\once \override Timing.TimeSignature.text =
\markup \line { \timeSignature #one \timeSignature #two }
\time #one
#})
secretTime = \tweak TimeSignature.stencil #f \time \etc
global = {
\alternateTime 6/8 3/4
s2.
\repeat unfold 5 {
