This is certainly possible, but unfortunately not completely out-of-the-box aka via configuration.
What you need to do is the following:
* create new cl domain for your deployment -- can be done via jboss-classloading.xml
* set default cl domain as your parent cl domain -- can be done via jboss-classloading.xml
* create parent policy for Module which sets your excludes -- needs some deployer / programmatic
This probably means you would have to create a new deployer which would create custom Module - to override the getDeterminedParentPolicy,
which would disable the usage of VFSClassLoaderDescribeDeployer --> your similar deployer should kick in.
You can have a crack at it, but let me know if you get stuck, and I'll help you.
