I'm not up to this level of knowledge in Norwegian yet, but I am sure there are many people who have a very in-depth knowledge of the language and would love to see stories added in Bokmal, especially since the Norwegian course is one of the larger and more developed courses.
Just a thought.
While I'd also love some Norwegian stories, I don't think we'll see them anytime soon, unfortunately. Norwegian is a fantastic course, but Duolingo seems to allocate more of its resources and experiments to the largest courses.
This isn't a decision made by the moderation team for the Norwegian course - it's a decision made by the Duolingo staff
