Have you tried \partcombine?
<http://lilypond.org/doc/v2.19/Documentation/notation/multiple-voices#automatic-part-combining>

If I understand correctly, it will do exactly what you want; if not, you could 
always provide us with a compilable example that we can debug for you.

\partcombine will only properly handle one pair of instruments at a time, but 
you can have an arbitrary number of staves each of which includes a pair of 
combined parts.

I hope this helps!
Kieren.
