If someone wants to deal with Lois's life after baby Clark is killed, I'm sure it would be ... interesting. Ditto Clark's reaction after Lois is killed -- but I wouldn't be reading them. It wouldn't be the Lois and Clark romance, and bleak endings to Lois and Clark fics don't interest me. I've never understood the urge to make the characters permanently unhappy. Even as a writing exercise.
