That wouldn't make sense because their back stories in the film universe are obviously far different from the comics version. Clint was apparently a SHIELD agent long before he ever met Natasha, and they were never criminals together. Natasha's confrontation with Loki made it obvious that she was an assassin of the worst sort, who burned down a hospital and killed and/or tortured someone's child. She is quite a bit darker and more sinister than her four-color counterpart. Clint was merely the agent who disobeyed orders to save Natasha's life.
One day I'd like Natasha to get her own film wherein her past can be fully fleshed out. It would be interesting to see her having to deal with the real consequences of her past actions without SHIELD providing her protection.
