I think Spiderman is more of a tank.
I agree that Spider-man does have super strength. Not to the degree of Superman, but strength far superior to "moral" men.
More of a scrapper? No.
He can take far more damage than a scrapper. he can throw around cars if he wanted to. He is more of a tank than a scrapper. Perhaps more of a brute, but that is a villain archetype and the thread is about scrappers gaining a tanker power set.
If you give super strength to scrappers then why not give it to stalkers, dominators, and blasters as well?
I think this falls into the same area as why scrappers don't have taunt.
