This is a question for the EMF newsgroup.
The UML2 metamodel is coming from an EMF serialization therefore if you just change the serialization you will get a specific metamodel. This metamodel will not be anymore UML but could cover DSL needs.
I didn't really investigate the use of stereotype during EMF serialization it could be possible that you would need to add some glue in the EMF framework code
