Hi Ben,

try:

\version "2.17.15"
\language "english"

#(define ((longer-script x) grob)
  (let* ((stil (ly:script-interface::print grob)))
  (ly:stencil-scale stil x 1)))

scaleEspr =
#(define-event-function (parser location x-val)(number?)
#{
        \tweak #'stencil #(longer-script x-val)
        \espressivo
#})

\relative c'' {
  c4 e f\scaleEspr #2 g |
  f e g f |
}

HTH,
  Harm
