I know this seems very unlikely due to the nordics not having that much need to expand as the russians did, but anyway. With any PoD after the Viking Age, how could, and what would be like, if a nordic country (let's say Sweden for example, after conquering Finland and asserting dominance over Novgorod etc) tried to launch a "conquest of the steppes", similarly to Russia? Could they succeed as much?
Also, it would be nice if it could be a "traditional scandinavian" country, so no Rus pretending to be norse instead of romans.
