Yes, but not declaratively, only programmatically.
This is how I would do it.
* declare both A, B as On_Demand
* install B --> ControllerContext --> http://anonsvn.jboss.org/repos/jbossas/projects/kernel/trunk/dependency/src/main/java/org/jboss/dependency/spi/DependencyInfo.java
* once you have DependencyInfo --> add http://anonsvn.jboss.org/repos/jbossas/projects/kernel/trunk/dependency/src/main/java/org/jboss/dependency/spi/LifecycleCallbackItem.java (LCI)
* this LCI should simply enable (and install) A
