spiderwoman's mask isn't the same as peter's, in fact other than the eyes, there's no notable similarity
She doesn't wear a spider on her costume, have you even look at it?
Everybody works in New York, the amount of folks who haven't is way smaller, not counting that most of her adventures don't even take place there.
She didn't get her powers from radioactive spider dna, she had her dna spliced with that of a spider due to her being poisoned by radiation(not counting her actual origins of being a spider who was shaped into the form of a woman.)
She also doesn't have spider sense.
You could make as much of a case of black widow being spider family as you could Spider-woman
