Not sure why you'd want to do that to a 1922 M2, but...
I'd try to duplicate something like the single shot adapter on the Winchester 52, with the angle/height set the same as the top cartridge in a Springfield magazine. That should be doable in a blind magazine, with some sort of adapter that you attach to the bottom of the action, or possible a shorter magazine that would fit inside the 1903 floor plate.
Not sure how Winchester did the 52D, but that might give you a different/simpler approach.
