Considering that she has no actual details in common with Sypha's outfits, other than she has boots, and a hood, (not compelling) I would have to say you're digging way too hard. The name and backstory is the best you have here, but it's by no means a recycle of a design. They're different in almost every way, to the point that characters from other unrelated games have more in common with her than this character does.
