Angus is a woman?

The male shortage has led me to think through my earlier idea of having one of the thanes as a woman because, really, she's a modern Scottish army officer. Eg Major Janet Angus. This has an added complication because Angus has taken on being killed by Macbeth in the penultimate scene instead of Young Siward. This creates problems around the 'man born of woman' dialogue. Anyway more thinking to do.
