I think often all you need is a clever \include structure and invoking
different .ly files, which apply different settings and both include the
same content, like
% print-large.ly
\version "2.19.53"
#(set-global-staff-size 20)
\include "score.ily"
% print-small.ly
\version "2.19.53"
#(set-global-staff-size 11)
\include "score.ily"
% score.ily
\include "music.ily"
\score {
\music
}
%%%%%%%%%%%%%%%%
Another option might be using the -e option to initialise a Scheme
variable, which then triggers a switch inside your .ly file.
