>Viserys isn't killed by Drogo
>Drogo dies and Dany kills herself at the loss
>Viserys is alone with three dragon eggs and no way to hatch them
>He sells one for a fleet and sells an other for an army. They aren't a big fleet and army, but they are enough to get the ball rolling. The third egg is emergency money
>Word spreads of the Exiled Targaryen prince sailing westward
>He is intercepted by Barristan and Belwas who tell him to go to Pentos
>He does so. There he might be introduced to fAegon
What happens from here, I can't say since I don't know what Illyrio's plan with Viserys was in the first place.
Let's assume Illyrio's plan is for Viserys and fAegon to be dual conquerors. Maybe he'd try to convince Viserys to be a supporting uncle councillor to a king fAegon. I doubt it'd work and it'd just make Viserys a liability, so he'd get killed off, his ships and army and last dragon egg taken and given to fAegon.

>Robb marries Roslyn and thus isn't betrayed by Walder
>Roose and Lady Dustin still scheme in the background, but have fewer opportunities now
Let's make it a bit more interesting
>In King's Landing, when Sansa thinks about plunging to her death and taking Joffre with her, she actually does it this time
>Sansa's death is kept a secret, just like Arya's disappearance, but the Lannisters have zero hostages now
>Cat still lets Jamie go because she doesn't know Sansa and Arya are both gone
>Tyrion isn't accused of killing Joffrey, so he doesn't have a trial, thus doesn't discover Shae in Tywin's bed and so doesn't kill Tywin
>At this point in time, Joffrey and Margery are not betrothed yet, so the Tyrells are still unaligned
>Stannis still goes beyond the wall and stops Mance
>Robb may use this to convince the Northern Lords that perhaps Stannis would make a good King
Whether the Northern Lords would get behind the idea, I can't say. Some would, some wouldn't, probably
Let's assume he manages to and steps down as king in the North in favour of supporting Stannis. Sannis comes south and joins his army, now they face Tywin together. A Baratheon and a Stark teaming up to depose a corrupted monarchy is powerful symbolism, which likely helps their cause.
When fAegon lands in the Stormlands, Stannis probably stays in the North and Riverlands with Robb, focusing on Tywin first

Tywin's reaction to fAegon landing would be really interesting. I don't see it outside of possibility that he'd try offering Cersei to marry him, only to have that shit get shut down immediately by Joncon.

Arianne and Margery both set out to marry fAegon and become queen. The rivalry of Reach and Dorne continuing ever more. But the dragon has three heads after all, so who's to say fAegon doesn't just marry them both. I doubt Doran and Mace would be happy about that though. In any case, fAegon's side will be really powerful, with the golden company, Viserys's army and Dorne/Reach or potentially both backing him.
