Definitely worth doing! Will get a note out this week.
I'm thinking of suggesting him alone and/or part of a swashbuckler series; that might open the door a bit more, perhaps (?) You're his biggest advocate Maria--working tirelessly, really!
My advice is to go on thetas premise that he is a legend of hollywood, which he is, and deserving of his own stamp. After we see what they have to say, maybe they will plan a series other than the Legends one that would include several people.
