Is it worth replacing original joysticks with hall effect ones?

I'm interested in modding some old Xbox 360 and PS2 controllers. I see hall effect sticks for sale online but I'm not sure if it's as easy as replacing them and being done with it. I've read that DualSense controllers require calibration or something. Is it a difficult task to mod game controllers? I do have basic soldering skills. Thank you. Also, sorry if this isn't the best community for my question. It seemed the most relevant.
