So….let’s parse who this could be. First, the criteria:

1. This is a twist on one, long-term character. 
2. This character either wasn’t on the show, got killed off early, or had their plotline changed dramatically, so it can’t be done in the show. 
3. This twist involves 3-4 characters. 

 Let’s make some eliminations based on these criteria:

• A+J=T – show hasn’t precluded it, doesn’t seem to involve enough characters. Don’t think so.
• Dwarf’s Penny/Tysha – Tysha got dropped, doesn’t look like Penny has been cast, potentially involves 3 characters. This goes in the plausible file. 
• A+J=C/J – show hasn’t precluded it, doesn’t seem to involve enough characters. Don’t think so. 
• Lady Stoneheart and Jaime/Brienne –  show doesn’t seem to be using LSH (prove me wrong, show, prove me wrong), and Jaime’s off in Dorne this season and Brienne’s doing something else in the Vale. And it potentially involves 3-4 characters. This goes on the plausible file. 
• Aegon is Real –  show doesn’t seem to be using Griff/Young Griff, would involve quite a few characters, but on the other hand does he qualify for “long term”? Putting this one on the maybe file.
• Jeyne’s Hips Don’t Lie? – well, show killed Talisa and her baby, it would potentially involve quite a few characters, and Jeyne’s a long-term character even if she’s not a main character. Putting this one on the plausible pile.
• Something with Sam – well, show doesn’t seem to be sending him to Oldtown, so there’s lots of scope there. Sam’s certainly around a lot of other characters (the Oldtown crew, Jon and the NW, etc.). The only thing here is I don’t see what the twist is. So putting this on the maybe pile.
• Something with Sansa – well, her plot on the show seems to be departing from what we saw in the Alayne chapter, she’s definitely around a bunch of characters, etc. And I could see a number of different twists having to do with LF, Harry, Sweetrobin, her kin, etc. Putting this on the maybe pile, but definitely on the top.
• Jon stays dead – Don’t think so. Both the books and the show seem to be going on a similar route in terms of him being stabbed by his own men. Also, doesn’t seem like the right kind of twist – you don’t need death to grow organically out of characters. 
• Something with Jon – however, I could see some other things happening with Jon. The show’s seemingly precluded him being revived by Melisandre and/or having her convert to Jon = AA, and that would certainly involve a number of characters. Jon leaving the NW after revival might also work. Putting this one next to Sansa at the top of the maybe pile. 
• Arianne gets greyscale – dunno if Arianne counts as a long-time character, since she was intro’d in AFFC. Also doesn’t seem like the right kind of twist. Don’t think so. 
• Daario – well, having him actually be Euron or someone else or riding a dragon or something might work, given that the show doesn’t seem to be casting the Greyjoys, and it certainly would fit his character. Putting this one on the maybe pile, but not very high up.
• Bolt-on – doesn’t seem precluded by the show, doesn’t seem like it would involve enough characters, doesn’t seem like the right kind of twist. Don’t think so.
• Something with Jojen Reed – Jojen not being dead might fit, as the show killed him off, and it would involve multiple characters. Not sure what kind of a twist it would be. Somewhere in the middle of the maybe pile.
• Something with Davos/Rickon/Osha – show’s not doing Skagos it seems like, it involves the right number of characters, although I don’t know what the twist would be. Putting this one on the maybe pile.
• Theon King – given the hash they’ve made of the Asha plotline, I could see Asha pulling a Torgon the Latecomer. Involves a number of long-time characters, show seems to have precluded it, twist fits both of their character arcs. Putting this one next to Sansa at the top of the maybe pile.
