Jack as a lifting device--very clever but unlikely.
Dick, Willie, John Thomas as slang words for penis are just very common male names and would have been even more popular percentage wise, when this slang originated, hundreds of years ago. Mickey meaning penis, is more used in Ireland than elsewhere, I think, but again, just a common male name. Might as well have used Paddywhacker to mean Irish penis.
