Nothoi probably couldn't hold it, but if they did it would dominant the other dutchies.
Ideally Wudenkin should go to Sint as a colony so they can have a good war with IVF while everyone else kicks the bejezus out of Enweil (who has had it coming for some time). Hell, so long as Matt and Squall get aced (and go to Enweil or IVF) Fronen can keep Wudenkin so long as they're willing to burn Enweil and IVF to the ground.
I agree, as things stand right now Nothoi wouldn't be able to take both Dyomoque and Wudenkin. I suppose a colony in Wudenkin is possible, but it would need nobles from more than just Sint to survive.
As for going after Enweil, that is a long trip. I wonder how long the north would remain resolved to make that trek before turning on each other.
