The cheapest way would be (using a syntax introduced very recently)
%%%%%%
sm = \tweak #'font-size #-4 \etc
{ <c e \sm g> }
%%%%%%

To comply with Lily versions older than ca. 2.19.25, use
%%%%%%%
sm = #(define-music-function (parser location m) (ly:music?)
        #{ \tweak #'font-size #-4 $m #})
%%%%%%%
instead.
