black rat as cobra training?

[Reticsrule]

PLEASE DO NOT TREAT THIS AS A STUPID OR IMMATURE QUESTION. i am just curious. i have heard people say that aggressive non venomous snakes are good training for venomous ones. i have also heard that this is completely false and nothing can prepare you for a hot except a hot. eventually i would like to get into venomous snakes someday(NOT NOW) and if i felt comfortable enough with the idea, i would like to someday get a cobra(probably monocled). i live in pennsylvania and black rat snakes are fairly common here. if i found an AGGRESSIVE 4+ ft. one and kept it and treated it as a cobra(use hooks, tongs etc.) would that provide any training for a real cobra? ONCE AGAIN IM JUST CURIOUS SO PLEASE DONT START FLAMING AT ME.
