Nope, never gonna happened. Overly simplified, a large part of Scandinavian history is just Sweden and Denmark engaging in one conflict, war or invasion after the other, and dragging the other Nordic countries into it (especially poor Norway, which has been conquered by both several times). So no, they haven't exactly been good neighbors.
