Perhaps a scientific experiment in Oscorp goes haywire. They could be testing some new technology related to body transfer or consciousness swapping. Black Cat and Spider - Man accidentally get caught in the experiment's field, resulting in their bodies being swapped. This would force them to adapt to each other's physical abilities very quickly.
In their personal lives, it would be chaos. Spider - Man has his relationships with Aunt May, Mary Jane, etc. Black Cat would have to navigate those while in his body. And Spider - Man would have to handle Black Cat's relationships with her criminal contacts. Their identities would be at risk of being exposed as they struggle to act like the other in their respective personal and superhero lives.
They could form an unexpected alliance against a common enemy like the Kingpin. The Kingpin has always been a major threat in the Spider - Man universe, and with Black Cat's knowledge of the criminal underworld and Spider - Man's powers, they could really shake things up in the fight against him.
If Black Cat and Spider - Man switched bodies in a fanfiction, it would be a total chaos. Spider - Man would have to deal with Black Cat's more stealth - based and morally ambiguous tendencies.

She might use Spider - Man's powers in more self - serving ways at first, until she realizes the true meaning of being a hero.
One common theme is the confusion that comes with the body swap. The character who becomes the black cat has to adapt to new senses and abilities.
