There's definitely not a concrete "yes" or "no" answer to this question. People are always going to be attracted to a wide range of things. They're also going to be turned off by a wide range of things. For the most part, I've noticed that women at the very least respect and adore men who crossplay. To them, it shows a sense of security, awareness of self, and open mindedness.
One of my best mates is a real manly sort of man who just happens to love crossplaying. His girlfriend not only likes it, she enforces it. She's always the first to help him research new and exciting characters. So yes, I think in many cases, it's possible that women would find crossplaying attractive.
