Yes of course.. but you will need to configure the applications to run in your own jboss..
Check the applications deployed inside the installer and then check the standalone.xml file ..
I know that there are some files specifiying the users available for the console, and depending your jboss version is how some dependencies needs to be removed.
You can take a look at the build.xml file to see how the resources are being moved and configured.
