His Mortal Life, Mortal Heroes - WSJ.com: "When Gemmell was a boy, a teacher read 'The Hobbit' to his class, turning Gemmell into a lifelong fan of J.R.R. Tolkien, whose characters became his role models. On a train platform one evening, Gemmell -- a big-and-tall fellow who once worked as a bouncer -- saw three men beating up a fourth. As he told the Independent, 'A voice inside my head said, 'What would Boromir do?'' He jumped into the fray and fought off the assailants."
This reminds me of Napoleon Hill he created a notional mastermind group of various great people in history. He would ask each in his imagination how they would solve a problem or what they would do in a situation.
There is nothing preventing us to create more then one set of these imaginary advisory groups: Why not have the Fellowship of the Ring and the crew of the Enterprise advise you on various topics. You could also have anybody even someone like this.
