Not only do you have the above mentioned issues, but you have to insulate the wires or whatever else you use. That will also affect the motor, plus you get inspectors wanting to verify that yes,that is a CIM in there, plus the CIM may be counted as part of a motor assembly, so you get hit on making your own motor. I don't think it's worth the effort, because by the time you get through th inspection process and everything else, it'll be Friday afternoon... A better option for more power might be to just have another motor that engages only when you want it to. If you really want to get an answer to whether winding more coils around the motor is legal, talk to Q&A. Oh, and all this leaves out the possibility that this whole thing might not work.
