I think you could do it....you would end up proxying the proxy created by the proxyfactorybean 
Code:
<bean id="yourManagerImpl" class="org.springframework.ejb.access.LocalStatelessSessionProxyFactoryBean">
.....
</bean>
<bean id="proxyCreator" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<property name="beanNames">
<list>
<value>*ManagerImpl</value> <!-- How do I reference a EJB -->
</list>
</property>
<property name="interceptorNames">
<list>
<value>loggingInterceptor</value>
</list>
</property>
</bean>
