Answer 1

I would be rather hesitant to do this. Please correct me if I am wrong and then I will delete, but it sounds like you want to maintain an A object along with a B object. If they indeed are not the same object, the "tying together" (that's a scientific term) you'll have to do would be pretty ugly.
