This is no more or less "REST like" than the above (I assure you!);
and yes it's possible (the issues then are to identify objects that
are not yet persisted to the server; and of course mapping the
"employees" to an EntityProxy class, representing the class+id couple
in the Place, and having dedicated "find" methods to retrieve the
object from the server, as without an EntityProxyId you won't be able
to use RequestFactory.find())

Yes.
That or writing your own PlaceHistoryMapper that won't use
PlaceTokenizer's at all (i.e. implement PlaceHistoryMapper in a
concrete class and not use the GWT.create() magic to generate the
implementation).
