I'd rather use
myTimeSig =
#(define-music-function (parser location frac)
  (fraction?)
  #{
    \once\override Staff.TimeSignature #'text =
    \markup {
      \abs-fontsize #14.5 \bold \override #'(baseline-skip . 2.5)
      \center-column {
        \line { #(number->string (car frac)) }
        \line { #(number->string (cdr frac)) }
      }
    }
    \time #frac
  #})

Is that one necessary?

and here just

    \myTimeSig 16/4

Well, that's nicer anyway.  But doing the simpler version simpler has
its charms.
