*Really* big orchestral score with lilypond ?

[Alexandre Beneteau]

Hello,

I am currently working on a orchestration with involve a really *big* 
number of musicians (4 solists, choral, and 12 percussionnists, each 
playing several instruments)....

As you can expect, even with "paper11.ly" everybody does not fit on a 
single page !

So my questions are :

- Is there a way to have a paper size < 11 ?
- Or is it possible to ask lilypond to write an a3 page and use psutils 
to resize it to a4 ?

Thanks in advance,

Alex.
