Was there any chance in Sweden and Prussia's histories when they could have formed a potential dynastic union? I'm trying to come up with either a Swedish Vasa ruled Sweden-Prussia, or a Hohenzollern Sweden-Prussia, and I'm not sure which one of those would be plausible. The Swedes may have to bargain hard with the Prussians in entering such a union, but overall, would the dynastic union allow Prussia to develop a rather, different kind of Germanic identity that is similar and different to the German identities of Switzerland, Austria and Germany proper?
