I don't really recommend that unless you have a truly complex website with very distinct differences in how the fundamental dispatching is being done or you have a compelling reason to keep several independent struts-config.xml files (which basically means that you're running multiple webapps).

So you can run multiple servlets -- or multiple instances of the standard Struts servlet -- just by adding mappings.
