Hi Dan, yes that would be the case re: stinking dead larvae, primarily from the smell of SHB larvae. If I was doing it, I would entice the bees into the box with a frame of brood outside the box & then place it in the box after a couple of hours once the frame is covered in bees. With that process, they will make a new queen. If the old queen eventually comes out, she might have a fight on her hands. I'd say she will probably not come out until the SHB has taken over & eventually drives the last of the bees out.
