Do you really think he'd go for a flat-chested impersonator with none of the honor that the one who she's impersonating had?
Minor spoilers for Fire Emblem Awakening:
In Awakening, at the beginning, she doesn't want to reveal her true identity, or that she is a girl. So she wears the mask and keeps her hair up to look like it's short, and goes by "Marth" in honor of Prince Marth (who during the events of Awakening is like 400 years old long dead or something like that)
