Sounds interesting to say the least. I know many would be disappointed, but need I remind you about Captain America? Technically he has no real super power either, he's been chemically enhanced (steroids?) to the pinnacle of human. While Batman worked out Steve went the Bane route. The rest is all training and years of experience. Widow is pretty much the same as our caped crusader; expensive gadgets and training. I don't think she has the tragic back story he does, I think she did it for the money. A mercenary for the highest bidder, or just spying for whoever. Been awhile since I brushed up on Black Widow lore. So yeah spy/assassin movie for a back story wouldn't be too far fetched.
Funny side note, in the original Avenger storyline Hawkeye worked in a circus and got jealous when Captain America got alot of attention. The archer became a villain when he was recruited by Black Widow. Funny, no?
