I am, at the present, living in Denmark and actively studying Danish on the state-funded courses, using Duolingo, and other means like reading, following a lecture course and conversations.
I will be moving to Norway in three to ten months. I have never studied Norwegian.
My goals are to be able to read fluently, to eventually (in three or four years would be optimal) be able give a lecture course in my discipline and interact with university students. I am not yet there with Danish, where my conversational skills are around level A2 (European framework), and reading is at around B level. My Swedish is slightly weaker.
For me, it is fine to be able to speak either Danish or Norwegian, and accent is not an issue, either. That is, I am willing to neglect Danish while living in Norway, with the assumption that if I come back, I will be able to pick it up again fairly fast.
What are the pros and cons of replacing some of my self-study of Danish with Norwegian? I am well aware that asking strangers on the internet to make life choices for me is a bad idea, which is why I am asking for the pros and cons, so that I will be able to make a more informed decision. (The government-funded courses in Denmark are at the moment free, so I will continue those for as long as possible. In Norway the similar courses cost around 3000 kroner for half a year, I think, and taking them is not an obvious choice, though it is a likely one.)
