Show status: Nah.
Book status: Seems possible!
The logic behind it: This one is book only, but is orbiting an actual George R.R. Martin proclivity to have slightly modified events repeat throughout time. The theory has to do with a tourney in The Hedge Knight, the first book of the "Dunk and Egg" A Song of Ice and Fire spin-off novellas that follow Ser Duncan the Tall and Aegon V Targaryen ("Egg"). In that novella, the two end up at a tournament for a 13-year-old lady's name day. The Lady Ashford ended up having five champions fighting for her that day (if you defeated her champion, you became her champion): Lyonel Baratheon, Leo Tyrell, Tybolt Lannister, Humfrey Hardyng, and Prince Valarr Targaryen.
Back in the novels (behind where we are in the series), Sansa is at the Vale where Littlefinger plans to marry her off to Harry Hardyng. Sansa of the books is also 13 and has been engaged to Joffrey Baratheon, Willas Tyrell (in the show, Loras Tyrell was briefly engaged to Sansa instead), Tyrion Lannister, and now Harry Hardyng. Which means she's right on track to marry a Targaryen next, if the historical pattern holds. Book readers are hoping it ends up being Aegon VI Targaryen (a character who didn't make the show), not a post-resurrection Jon. Show watchers dodged this possibility, instead suffering through the Ramsay/Sansa marriage instead.
