Can not say anything about making music-function,
but, maybe, markup-command will fit?

#(define-markup-command (trillflats layout props) ()
  (interpret-markup layout props
    (markup
      #:tiny
        #:center-column (#:flat
                         #:musicglyph "scripts.trill"))))

Then:
g4(^\markup\trillflats
