Is it possible to use lilypond-book options with the LilyPond module?

[Tao Cumplido]

I would like to reduce the staff-size of the lilypond output and using #(set-
global-staff-size 16) in the lilypond code doesn't work so I guess I need to 
change the lilypond-book options [staffsize=16] but I can't seem to do it from 
within Lyx.
