Xbox Series X Gulikit TMR Joystick compatibility with Elite controller

This question is regarding the warning about compatibility of the Gulikit TMR Joystick with the Xbox Elite series controllers. There is a warning stating "Not recommended for Xbox Elite or Xbox One controllers due to unavailable software for joystick calibration." This doesn't make any sense because the Elite controllers actually use the Xbox Accessories app that has built in joystick calibration software. The very same software I see being used to calibrate the joysticks for the regular Xbox non-Elite version controllers.

I'm assuming the actual issue of compatibility is the different style of stem that has a thread to screw the Elite series thumbstick cover on. If that is the case, then my second question is if it is possible to replace the stem of the Gulikit thumbstick with the stems from Elite thumbsticks or not? I would really like to be able to replace the thumbsticks with TMR type if possible. The product page states that lack of calibration software is the issue, but I believe that is incorrect and the real problem is the stem difference. I would appreciate any feedback from anyone that has attempted this or knows enough about the TMR joysticks to know if they can be modified to fit the Elite 2. Thanks.
