If the steerer tube thickness is the same, I think you can just have the threadless fork threaded by a frame maker with the correct die. I believe that the outer diameters of 1" threaded and threadless are the same (plenty of people have just installed threadless stems on threaded forks, despite warnings that the steerer tube is weaker at the threads). If steerer tube thickness is the same, then the stem should fit in the steerer tube once the nut is removed from inside the steerer tube - you can check this yourself with a threaded style stem. If the steerer tube is too thick and the stem will not go in, you can have the tube reamed or honed to size. If the steerer tube is too thin, then you may be looking at a new fork or having the steerer tube replaced in the existing fork.
