First off, don't call it EJBObject as that word has special meaning in
EJB, and is not what you're referring to. "Entity instance" or "Entity
object" is much better.
Anyway, yes you can do that. You will need a separate class to contain
the state for you (unless you're happy with sending Object-arrays..)�.
For example a CustomerBean would have a CustomerData which can be
extracted from the CustomerBean and also be given to a CustomerBean to
set the state.

You can send a callback to the client which can be used by the EJB to
invoke the client.

All interfaces must be public. I suggest that you solve this by letting
the public bean change identity to a system identity, and then set the
security of the "private" beans so that only the system identity may
call them.
