That's a no go. Sho's got a thorough background check thing going on with his spy division and a spy working in the base already. He'd have known that otherwise he'd had come up with a different plan. Having them know about this will end up getting all of the four characters in the base killed, and botch the landing party that's set up. The commander is known for his anti-japanese rhetoric and is popular among britannian pure blood nobles but hardly that big in the food chain of things.
