Maverick in web services

I've been reviewing the Maverick code base and was wondering how
difficult it would be to tailor it to web services.
 
I need to integrate a MVC framework _behind_ a SOAP web service
interface to be used in building applications.  Basically, requests come
into the web service with parameters, the web service processes the
request and returns a response.  The response contains a String of xml,
html, etc.  For arguments sake, lets say the interface is:
 
Response process(Request req);
 
So, it's very similar to the service method in a servlet, but the result
is returned instead of being included as an argument.  The Request and
Response objects are not servlet related, but they are similar.  I want
the MVC framework to dispatch the req to the proper Command based on a
command parameter in the request (or something similar), possibly chain
commands, and then load views/transforms all based on a config file.
Maverick seems to be a perfect fit, although it seems to be fairly tied
to a servlet container.
 
So basically I want a MVC architecture totally independent from a web
container (i.e. no HttpServletResponse references, no ServletContext
references).  I was hoping someone experienced with the Maverick code
base could give me some estimate on the difficulty I would encounter
modifying Maverick to work in this environment.  Or if you know of other
libraries I could use that would be great.  I've looked at Struts,
WebWork, and Maverick.  Since Maverick seems to be the simplest, I
thought I would start there.  I'm looking for something along the lines
of the XWork project at OpenSymphony, but unfortunately that project is
not yet stable.   Thanks!
