"Proc" stands for "Programmed Random OCcurance". It does not even vaguely apply to anything Magic cards do. Don't use it.

Would it be possible to make a Phantasmal Image into a legendary creaure, creating a possibility of have four legendary creature out at once? or Clone and Cryptoplasm
Among other characteristics, Phantasmal Image copies the original's name, which is what the Legend Rule keys off of. Sakashima the Impostor and Lazav, Dimir Mastermind keep their own names, so they would do what you want.
