Yeah the one thing Margaret has going for her is she at least looks fairly different than the other strawhats with her extremely light hair, her different drawn styled eyes and different hair style. It wasn't till this chapter that I felt Hancocks looks could actually mesh ok with the strawhats visually. Thats when she showed off her seduced face at the end. Really at this point because of the fact it can go either way, I would conclude that Hancock wouldn't become a strawhat if she ended up having jet black hair like Robin. But I think she might have Dark Blue or Purple hair especially if her design is based off that one Color drawing Oda showed off a while back with lady in the dress with silver/purple hair and a large boa wrapped around her body.
