There is an example showing the changes needed to set polymetric music of
the type you describe towards the end of this section of the Notation
Reference:

http://www.lilypond.org/doc/v2.17/Documentation/notation/modifying-context-p
lug_002dins

I think that shows all you need to write a 9/4 measure against three
3/4 measures.  But the main section on polymetric notation showing more
complex arrangements is here:

http://www.lilypond.org/doc/v2.17/Documentation/notation/displaying-rhythms#
polymetric-notation

which explains all you need to know (I hope!)
