Best case scenario (imo) is boots on ground cooperative with South Korean troops, bringing fucking culture. There's a reason missionaries are able to set up such successful excursions into 3rd world countries. They bring food, technology, education. The new PM of South Korea seems very benevolent, and I bet would let North Korea remain their own state if they so chose to.
Muda Muda Muda Muda Muda Muda!!!!
