I'd be interested in this game, maybe I could try France?
On possible changes, these are the ones I made to the AoM scenario:
- remove French cores on Navarra and Gerona (*no* reason to have them)
- remove French core on Alsace (is added by Chambers of Reunion)
- remove Swedish core on Kurland (this one is actually added by the Kurland succession)
- remove Brandenburg's cores on Poznan and Silesia (those are well off being added later)
- give Spain a core on Artois, Franche Comté and Roussillon
- give Russia its core on Livland (it gets it in the Fate of the Order)
- create a truce between Spain and the Netherlands that lasts until 1621 (the 12-years truce)
- make the Palatinate the leader of an alliance with Hessen and Württemberg (i.e. the protestant Union that did NOT include Brandenburg or Saxony)
- put Baden, Strassburg, Würzburg, Köln and Münster into the alliance of Bavaria and Austria (so that we have a catholic League)
- make Denmark the leader of an alliance with Holstein, Bremen, Pommern, Mecklenburg and Hannover
- make Oldenburg and Holstein Danish vassals
- (essential) make Bohemia independent and protestant (but an Austrian vassal) so that the Thirty Years War will happen
