Not really simple. But it can be done by redefining the stencil:

\version "2.21.0"

#(define (fraction-with-gap gap)
   (lambda (grob)
     (let* ((frac (ly:grob-property grob 'fraction))
            (num (car frac))
            (den (cdr frac))
            (fontsize (magnification->font-size (/ (- 4 gap) 4)))
            (baseline-skip (+ 2 (/ gap 2)))
            (m (markup
                #:vcenter
                #:fontsize fontsize
                #:override `(baseline-skip . ,baseline-skip)
                 #:center-column (#:number (number->string num)
                                   #:number (number->string den)))))
       (grob-interpret-markup grob m))))

{
  % The number 0.5 can be changed. It’s the size of the gap in 
staff-spaces.
  \override Staff.TimeSignature.stencil = #(fraction-with-gap 0.5)
  \time 3/4
  s2.
  \time 5/4
  s4*5
}
