It would have been interesting to have seen a Mummy story on the show, but I think I would have replaced the 1970 PT story with the mummy idea.The show already had a vampire, witch, werewolf, man-made creation, phoenix, and a lot of ghosts......why not a mummy?
[spoiler]Wasn't Quentin turned in to a mummy at one point in 1897? I can't really recall the actual details, but it's after Jenny kills him I believe.[/spoiler]
Nope, he was [spoiler]turned into a zombie[/spoiler]
