Maybe afterwards.
The scenario I'm focusing on is as follows:
In Gustav Vasa's Will event Finland is released as a vassal, also, tax reductions in Bergslagen and Svealand (to represent Karl's and Magnus' duchies who weren't as active)
As the conflict between Erik and John intensifies things get a bit more dicy (I'll probably have to rework the Fate of The Teutonic Order event, so that Finland too might get a shot at Estland)
Once John's treason progresses far enough (there should be ways to keep the peace with Erik) Erik has the option to invade his duchy or not, if he doesen't Finland stays as a swedish vassal (with cores on) and uses John's Vasa Line as monarchs (and leaders, possibly other swedish generals hailing from Finland might also be included) once that line is extinguished they get the choice between joining sweden again (historical choice) or electing a local duke (war with Sweden, - stab, revoltrisk, desertions)
If Erik invades the Duchy has the option to surrender (inherited by Sweden) or fight on, (- stab, revolts, desertions, vassalization is broken) If Finland still exists at Erik's historical fall John becomes King (as by that time Charles and many others would surely have moved against Erik) and John has the option of either fully incorporating the duchy into Sweden again or keeping it as a personal fiefdom (keeps it as a vassal with his line as the default monarchs) if Finland exists when Sigismund is overthrown they have the option of submitting to Charles or to Sigismund (submitting to Charles means inheritance, to Sigismund means vassalization to Poland) They keep the polish vasa-line as monarchs and once that line dies out they can either join their respective realm (Sweden or Poland as things turn out) or choose to strike out on their own (in which case some other kind of monarchs will have to be wakened)
