But the articles I read said the Finns would never accept a swedish prince due to the lack of support from Sweden during the finnish civil war.
So, no chance for Wilhelm, Maria, Lennart and all.
Besides, Finland had been part of the russian empire so they might not like very much to have a russian queen.
May be a danish prince would fit, but then, Sweden might find itself "surrounded" by Glucksburgs in Dk, Norway and Finland, and object.
Pr. Harald could have been the logical option.
Republican France might oppose to Pr.Valdemar or his issue as such choice would have made of Marie d'Orleans a Queen or a Princess-Mother
