Welp, I finally pulled apart a couple minibucker reissues that I had and the coils do interchange, with one small caveat. Because the positions of the polepieces are different on the bridge and neck pickup, the transplanted coils will have the leads from the coils on the side away from the terminal strip. You can do the proper solution and put the slug in the polepiece slot, of you can solder in longer leads to the terminal strip and call it a day. Which I will do. Pics tomorrow.
