I find these kind of generators oddly addictive too. I wonder if it would be possible for all three of your loglines to be worked into one storyline... maybe the debutante (the secret daughter of the assassin) goes to a high stakes poker game with her roommate (the adopted daughter of the junkyard owner) where they meet a mysterious woman (the sorceress) who works with a gynecology practice as their "fertility" consultant ;-)
