I agree with Lionel. Having spent hours in the archives on this list, and then doing my own trials based on what I learned, I think it fairly easy to introduce a queen into a drone laying hive if you put at least two frames of mixed brood in with her, and lots of smoke, and scratching some honey comb with your hive tool to give the bees something to do besides killing your new queen. But as he said, the method you propose has a very high percentage chance of working. Depending on your history and location, make sure that Foul Brood didn't kill your queen. If you think that was a possible cause of her death, put one of those medicated patties in between your the two boxes when you add the top one.
