Sounds like I'd have to go with the owner to the FCC, and create a new allotment for Bremerton, for a class D translator.
Because that's not how it works. Translator applications can only be made during a filing window. The last window a fews years back over whelmed the commission, and there are still a large number of translator apps that are in limbo, MXd to others. And now, many of those applications (including a few of mine) may get tossed after all this time because of changes inthe LPFM procedures.
The second point, which I made many posts ago, is that AM stations can only utilize FM translators that were in existence before the Rule allowing such. You would have to find an existing translator, and figure out within the rules whether it could be moved so that the contour matched the AM contour.
The third point is that it has absolutely nothign to do with how good the AM signals is at night. It is all determined by the AM daytime contour in the FCC database. An AM with 1kw day, 12 watts night, will have a 24 hour contour to match the AM daytime contour.
