Tomcat Interceptor to forward soap messages

I have two CXF web services: Old Web Service A and New Web Service B. I am wondering if it is possible to use "org.apache.tomcat.core.BaseInterceptor" or another interceptor method to forward soap messages to B before they reach A. I don't want to change the configuration/code of A or B. I just want to redirect soap messages without consuming them. Thank you in advance.
