Eluze's example works --- with 2.17.25

For 2.16.2 you could use:

\version "2.16.2"

music = \relative c' { c d e f }

staffSize = #(define-scheme-function (parser location new-size) (number?)
#{
  \with {
    fontSize = #new-size
    \override StaffSymbol #'staff-space = #(magstep new-size)
    \override StaffSymbol #'thickness = #(magstep new-size)
  }
#})


\new Staff \with { \staffSize #-16 } \music

\new Staff \with { \staffSize #16 }   \music

> What would a "new-size" value of -16 mean?

Well, what does \fontsize #16 (#-16) do in \markup? Making it larger (smaller).
Here fontSize, 'staff-space and 'thickness of the lines are modified.
I feel I don't get the point of the question.

There were some discussions about layout-set-staff-size some time/years ago.
Can't find it right now.
