Rather then a kindom, in my opinion, she'd proably become like the HEAD of her own religion or something xD lol. As said in the manga, she becomes a bigger threat to the royals by having that much power and influence over people, making them split their fait between her and the king. This will proably lead to some kind of war or something(⊙…⊙ )
Maybe (I have a feeling) Yona would establish her own kingdom somehow. After all, every influence that she made to many people have become a source of their hope. Surely, people will follow her for that. (not because she was a daughter of King Il but as Yona, the Queen of the Breaking dawn :) )
