Proud to be called a "Lawyer".
I hesitate to put too many eggs in the Hannity basket.
I think Cohen may have used Hannity's name as a way to "build up his resume". Cohen was being accused of not being a real lawyer. He needed names to counter that accusation.
Because, if he was not a lawyer, there could be no attorney-client privilege. If there was no attorney-client privilege, all the evidence was open to examination.
Perhaps Cohen thought Hannity would go along with his plan? Obviously, they did not discuss the matter before Hannity's name became public during the hearing. At first, Hannity seemed to go along with the plan. He said they may have discussed 'real estate" and he may have "paid him ten dollars", he said, as if that would make their arrangement official? Then he changed his story. He never had any business with Cohen and he never signed anything and there was never any arrangement between them.
Hannity's statement left Cohen with only two clients, both of the hush-money variety. This is not lawyer business.

Much as the absurd allegation that "the MIC wants Americans to die in Eastern Europe!" Just Ain't So, part II. 
Dig in, though. And dig the hole deep... in case we need to remove our narratives from view temporarily.
Bless your heart.
He is a mob lawyer....
