Aly and Lyanna if Aly never married Ned?? I think in an au where they're together, they'd be so cute!! also the angst potential perhaps??
Alyanna!! My darlings!! There is technically an AU where they’re married, my sedoretu AU, but that exists mostly in my head.
I can see an AU where Ned doesn’t ask for Aly’s hand before Harrenhal, and she and Lyanna hook up there. In my work, Lyanna at least leaves with Rhaegar willingly, but if she’s romantically involved with Aly, I don’t think that would happen (so no Jon). And that means no rebellion, either. So Brandon and Catelyn are Lord and Lady of Winterfell and Robert is Lord of Storm’s End.
My favorite way for this to end is Ned and Aly still get married, and move to Storm’s End. Everyone knows that they’re sleeping with Robert and Lyanna, but since no bastards can come of it, and Lyanna and Robert do have a couple of children, no one cares.
If you want more angsty, though, there’s also the possibility that Rhaegar straight up kidnaps Lyanna. In this case, I feel like Aly would have been with her when she’s taken, since she’s not going to meet Rhaegar by choice, and thus Aly would also be kidnapped. I think as soon as Rhaegar leaves the Tower of Joy, Aly makes a plan to escape; she’s friends with Ashara and Allyria, after all, so if they can get out, she and Lyanna can go to Starfall. Now, this raises the question of Jon. Does Ashara claim him, letting everyone think she slept with one of the Starks? Maybe. But the more likely option is that Aly claims him, saying he’s Ned’s (because to say he’s Brandon’s means she slept with her cousin’s betrothed and that’s pretty bad). I like the idea here of Alyssandra being kidnapped with Lyanna being enough to get Hoster’s support, so the Nedcat wedding hasn’t happened yet, and once again we do get Nedaly due to Jon. (Ned goes along with the lie to keep Lyanna safe.) Robert still marries Cersei because politics, Catelyn marries Stannis also because politics, and Lyanna goes home with Aly and eventually marries some Northern lord so Ned doesn’t look too hard at her relationship with his wife.
