I think what you are talking about is having multiple appearances of the same AOR on a user agent. This is certainly possible, and is discussed in the (newly reissued) draft:
http://www.ietf.org/internet-drafts/draft-anil-sipping-bla-02.txt See section 5.1 for example. You can also have more than one AOR shared between user agents, but I'm not sure that matches your two-active-calls scenario.
