Do you really need to create those WAR files. I had similar thinking before, but I have found a different way to accomplish the same result by creating new resources into apache server. Those resources, in turn, can talk to my EJBs.
It appears to me as if you are trying to do hot deployment in production server. The hot deployment feature, if I understand correctly is only useful during your application development.
IMHO, I do not recommend deploying gigantic WAR files to JBOSS, especially hot deployment.
