Mechanically, both are assembled the same way. The only variation would be the early Federal Electric/Enterprises Model 2. They had a sand cast motor frame and stator vs. the later die cast and also different brush holders. As long as they look mechanically identical you should be able to just swap the rotor and stator. If you want to pull the rotors from the motor armatures that is a little bit more of a complex job as the rotors are pressed on to the armature shaft.
