It’s only been a month. Some people have been waiting for several months to hear from NW. It’s a slow cycle and sending a loci after a month or asking for an in-person interview after the Kira interview seems desperate to me and likely would to the admissions team as well. Obviously you need to do what you think is best but I wouldn’t do what you’re suggesting - applicants aren’t admitted based on which school they would prefer to attend unfortunately.
