First, your subject line appears to be wrong to me: "everyone"
other than honeypots do not greylist.

Second, if I correctly understand what you are proposing above
(and it is possible that I do not), why do you believe that the
spammers will cooperate in behaving the way you want/ expect?
They have about zero incentive to go to extra effort to not send
mail to particular addresses unless doing so will net them a
_huge_ (think severals orders of magnitude) increase in the
number of messages that get delivered.
