You know, the kick in the pants is that most TR games are awful, but since the first few didn't present her as a bad character I think that made the games better....yea, and fine, she had a rack you could get smothered in probably helped in early days.
Some very good jokes made here. While the Mr Brain-Hat joke is pretty silly, it works with the presented character of dear Miss Croft. Also, I like your idea of spouse for her. If nothing else, it would make one hell of a Jason movie.
