AMS-BGW makes sense. Feeding AMS-BGW from DTW also makes sense. NW operated DTW-AMS-BGW makes sense especially if the AMS-BGW segment also carries the KL code. However, a KL operated AMS-BGW segment carrying the NW code would make even more sense and this is what I expect if both carriers receive permission to operate the route.
A hypothetical DTW-BGW nonstop would, IMO, make no sense.
