Without turning it into a wank or going completely ASB, is there any way this could have happened?
No, the problem was that Russia was willing to fight until Sweden collapse, and because the peace with Denmark only lasted 7 years, Russia only needed to keep things going until then and Sweden would be cut off from external support and trade.
You need a earlier POD, if the Assault on Copenhagen in 1659 succeed, they can force a peace on the Oldenburgs before the Dutch can stop them and end up being crowned king of Denmark-Norway (letting the Oldenburgs keep their domains in Schleswig-Holstein). The result would double the Swedish population with people speaking the same language and sharing the same religion.
