I think it's really important to remember that design patterns are suggestions and not absolutes. If they can be modified to better fit your needs then they should.

When one of your observable objects will notify it's observers it will simply loop on a list of references to tell them to update. It really doesn't matter if these references are shared with other observable objects.
