yes you can switch them. but its recommended to get a pair of new analog sticks so you dont have to open it again when the other side fails

did it with a philips 00. Just be extra careful and push down hard so the driver does not skip and strip the screws. I would recommend getting a prying tool and plastic tweezers. I removed the casing by hand and removed and installed the ribbon cables by hand which took a while and was a big pain in the rear end.
