Usually the only file you need to resign is the save data '.bin' file. I could be wrong but this is how it works for most games. It's not going to matter if you resign all the files and copy them to your PS4, it will just overwrite your personal game setting with the settings the owner of the save chose and then you can just change them back to yours.
