The aspects are bound to the delegate classes anyway, not the JBossXXX classes. But I don't think there's a need to create subclasses. I would just use the current classes. BTW the hierarchy of Connection/Session/Consumer etc is already maintained using the org.jboss.jms.client.state classes by the StateCreationAspect, so you could hook into that to make your life easier.
