I oppose too many edits. If your wife is old and you deperately need an heir, use ingame methods to resolve the issue. Worst case we rehost and he plays his brother.
4) Savoie and Upper Lorraine transfered to France from Germany
5) Something transfered from Flanders to Brabant
Brabant will also need a transfer to France.
Don't give them provinces from Flandern though. Upper Lorraine has 10(?) provinces at start so editing the two northermost to Brabant might be better. Flanders may be rich but it has few provinces.
