First I would make a backup of the rom as close to the way you like it as possible with what ever recovery you are using. Then store it on an ext sdcard or PC. Then you can just do a recovery restore when you want to change back. Mine is on a 32GB ext sdcard, which it seems like a I do a system restore via recovery backup once a day because of all the new things I try to flash. OR use a root explorer type file manager copy and paste the original dialer .apk to an internal or external sdcard. Then you can delete the new one, copy and paste the original back. Be sure to check permissions, they need to be reset to original settings, then power down the device, and when it reboots it will run the original dialer.
