This would work just fine, yes. You can either use the aspects of an 
object that it already has (by casting/invoking it), or you can attach 
any aspect to it as necessary. I.e. either the above (which is an 
example of dynamically attaching aspects and then using them), or you 
could do:
User user = IndividualBuilder.getIndividual("urn:user:dim");
user.getName();

ACL acl = (ACL)user;
acl.check(..);
