I'm aware that there are many Spider-People of various flavors (see Into the Spider-Verse) and all kinds of storylines where others have been temporily imbued with Spider-Powers.
Lo and behold, Black Widow is named after a spider...
Have there ever been any storylines where the Black Widow has Spider-Man-type powers?
In this case, Spider-Powers must rise above the level of super strength, resilience and reactions (unless they are specifically imbued by interaction with a spider or a Spider-Person). Examples of acceptable powers regardless of how received would be skills like web-slinging, wall-crawling, and Spidey-sense.
