I hope at first the game will make sufficient money to continue and it will be worthwhile to add some minor nations with patches.
Regarding the colonial/influence map mode I have an impression there should be some better tune for colonial/influence relationship for Ottomans/balkans Russia and Austria triangle. Historically balkans were under the influence of Russia/Austria and by a very small margin Ottoman. All these actions with some possibilities for annexations. If the game simulates influence/power struggle in the balkans it will be worthwile to play with Ottomans, only if other great powers doesnt interfere this influence. Historically there were no other Great powers other than Austria/Russia and OE( before) had the influence or need to. I think this change should be in the grand campaign not scenarious.
I have read writings of McNaughton(Researcher?) mentioning it wont be worthwhile to play
unorganised nations or no point them adding to playable nations list. if that's the case I give my vote to Montenegro. Pros: moderate-good military power/secular. all kind of fortune waiting and Not only it is playable in the 1850 start but have a
minor-organized trait.
