You should be able to have your bean implement all of the methods for all of the interfaces, then deploy it several times, if that's your question. That'll be accessing the same data for the same key values, so you'll need to use 'select ... for update' syntax and/or an optimistic locking scheme to manage concurrency.
On the other hand, if you want to have a single _instance_ implement all of the interfaces and cast back and forth polymorphically, that you can't do in EJB.
