The Inspiration of Rassilon

Username: daystarsearcher
Era (if any): Three and/or Four
Characters/Pairings (if any): Sarah Jane, Liz, Jo, possibly Three or Four as well
Plot Bunny Summary: Like the subject line says, I just finished reading this history of Nancy Drew's authors. And it is so very, very clear to me that Sarah Jane traveled back in time to the 1920s and served as the inspiration for Nancy Drew. (Actually, now that I think about it, LIz isn't a half-bad candidate either, if you focus on the demeanor and style more than the crime-solving. So maybe Sarah Jane would be the boyish, adventurous George? And Jo totally could've been the giggly, goodhearted inspiration for Bess.)
Any Other Notes: Also, Harriet Stratemeyer (head of the syndicate that published Nancy Drew) has definite parallels to Jo Grant, with the privileged background (and accompanying blindspots) and the can-do attitude and the desire for everyone just to be nice and get along. And Mildred Wirt (the original ghostwriter) was a fiercely independent journalist, clever and proud and hard-working and filled to the brim with gumption--she basically was Sarah Jane. So maybe the story could be more linear, about Jo or Sarah meeting these women in the seventies, and being inspired by them.
