Refactor Web Explorer so that all the Java code and static content resides in an external jar

I'm using the Web-Explorer from Modeshape in my project because it's a very nice and helpful JCR frontend during developement.

But I don't use any Modeshape bundle but only jcr-repo and the explorer.

So what I did is I cloned the Web-Explorer war into my project, modified the configuration and then used a maven uberwar to bundle that and my own application war.

It's all working fine, only downside is, now I have a clone of the Web-Explorer Java code and have to manually merge changes to the GWT code.

Therefore my question / feature request: Would it be possible to put all the static resources and GWT Java code of the Web-Explorer into a jar so that the Web-Explorer war gets skinny (only defines a servlet that is in the jar)?
