I don't think that sansa wants that, she did offer the lordship to Jon and she has what she wants for now, and Jon just want the title for the war of winter.
About legitimacy. Fuck legitimacy, power begets power, the targs aren't legitimate, they are just conquerors, just as the baratheon are usurpers. Whomever claims the throne and holds it is the rightful one. Considering that the economic aspect has been swept away, and now Danny has the biggest army and the dragons, little finger is not in a good position.

She could always just put the finger and leave it at that.
That's actually exactly where I was going with it. Rober won it by force, but he did have targaryan blood. Beleif is also power, and if people believe that legitimacy is inherited then lines and families do have power, of course unless you have military power.
Danys army is only powerful thanks to her dragons, but her dragons can be killed just like the giants can. If you read the history of ASOIF you learn that the dragons actually became extinct thanks to the maesters. Aego the conqueror took all of westeros with only 3 dragons and a very tiny army. That was the first time westeros saw dragons so he took the entire land with shock and awe.
many years after that event…?Give it some time and humans devised techniques and weapons against them, thats why all the dragons skeletons lie under the red keep and everywhere inside, they are all extinct..until danyrys. I don't want Danys conquest to be a repeat of Aegon the Congueror, it would be a fucking snoozefest. Bottom line without the dragons the armies of the Westeros are way more experienced and better equipped. The army of the tyrels or the vale would be able to win against them. I wouldn't count littlefinger out.
I disagree with you about sansa. That's what she did initially, but once everyone started cheering for jon snow she projected herself and what it would feel like to have so many people root for you. Sansa has always been in the backstage, watching everyone get what they want, while she remained a pawn. Sansa doesn't want that anymore, she wants to be the player herself. During that moment you see she is kind of disappointed because she did help win winterfell for Jon snow. And the eye contact/facial experession with Littlefinger was exactly the symbolic gesture of kind of expressing what Littlefinger said earlier, about doing something with your future. That future includes sansa being in control and making something of herself instead of watching the sidelines.
Besides, from a narrative perspective what else are going to do with the starks now that they have back winterfell? The lannisters held on to (and still do) the kings landing for quite sometime and that won't change for a while. But what made them interesting was the internal conflict of the family: between jaime and cersei, and between tywin and tyrion. You need that internal conflict otherwise it would be a snoozefest.
what else are you going to do with the starks, you need that internal conflict. And this conflict is definitely going to build up with Sansa and jon. Sansa is a true stark, but Jon who is only a bastard and not even a true stark now is king of the north. That's ought to make Sansa a bit jealous.
Littlefinger succeeds when he becomes the bridge between different groups while making sure the groups themselves don't talk with each other without him. He thrives in hostility between houses not unity. I am not sure how effective he would be as a king if there was a crisis in the kingdom with a credible alliance against him
Littelfinger thrives in chaos because thats the best way to gain power. If there is chaos then the stauos quo is destabilized, making it easier for new people to gain power when in most confusing times. Like you know through many examples throughout history where people perform coups and win over power.
Also, Im guessing you're talking about the Tyrells? Their fates are tied together according to queen of thorn, as long as Littleifnger doesn't do anything against the interest of the tyrells she won't do anything against him. Plus, now with the entire family completely gone what does she care anymore besides getting revenge for her family? The tyrells I assume are out of an heir aren't they once Olena dies. Yeah, it actually makes perfect sense if Olena dies it means someone can easily swoop in and take control of one of the most powerful houses in the westeros.
THe entire future small council will look very different, with so many people dead (I predicted this before). But as long as cersei is alive not many people can manuver for power around her especially with so much parnoia and distrust. She needs to die too, which Jaime will achieve.
But if jaime does kill cersei what would the otehr houses seek revenge on? A non-existant house? Most of the lannistser are gone or dead. Which means Jaime will get the stick end of it from a bunch of people who hate him simply via his association with the lannister family, even though he'll probably save the entire city twice. Either way, something interesting will happen with Jaime that will make is feel for him whatever the consequences/outcome of his character.
