The quick answer I thought of was that you need to implement your own 
derived version of BaseDocTemplate, I think.  When I looked at the 
multibuild routine I remember needing something that told it the build 
was done and the only way to do it was my own implementation.  Now this 
may be unreleated to your problem, but it is what came to mind without 
further investigation myself.
