This idea has been developed and deployed to Canvas
When making multiple quizzes, instructors often wish to use the same settings (e.g., time limit, whether correct answers are revealed, number of attempts). It would be useful if there were a way to copy or clone an existing quiz, without copying over the questions themselves, into a new quiz to retain all of these various setting. This could be done in an intuitive fashion by adding a new option to the pull-down menu for an existing quiz. Currently this menu includes Edit and Delete, but could also include "Copy" or "Clone."
