I am just going to talk off a whim here, without being up to date on much of the specific story structure.
If they were to gather all the individual story line associations, over the course of each book, or multiple books. They can generate a concentrated delivery off the point of interaction.
Build the innocence of the main characters, being normal, apart of the world, and crash down on them with the chaos of the evil forces. Which disrupts them of their homes and lives as they know it. So thats Bel Tine, where each character gets the press of their characters interwoven.
Then have Moirane and Lan be the guardians of the depths to come, as they go on their way to Camelyn. They can splice that by a background story stream, of Shayoul ghoul, and Artur Hawkings.
Then when they get separated, Rand can start having nightmares and dreams associated with what is going to go down. To the active world around them. Interactions that dictate the course of what plots are being taken against them. This will be a great envelopment, to the atmosphere of the world shifting in this current age.
With the use of some foreshadowing of talents etc, after being associated with the Elayne/Andor royal concept. He can be teleported, via dream traveling. So let’s say Moirane and Lan and some of the crew have to take the Ways, or go to Shadar Logoth. where they need to gather at the borderlands and meet the Borderlands.
For whatever it was that they were doing in (vague here on time line) the tainted city, or traveling the ways. Rand can realize the severity of his circumstance, and get taken on the high road from there. Whether that means, he meets up with them at the borderlands, or diverts from having to go to the borderlands entirely at that point, and whether that means he can teleport others with him, on the bubbles of his powers coming to the surface.
It can arc a lineage of events where each person gets there specific assembly to their roles. I.e Moirane taking Egwene and Nyaeve under her cusp. Rand can be with Mat and Loial and Thom. It can come to pass to the development of their characters, where they will be able to leech into accounts of the other series, and produce skip points or concentration points.
Lets say for the sake of association. Mats taint produces a conflict, that has him and Rand struggling, in an epic turn of character. Where it has been revealed the depth of evil the blade produces. Rand can be struck by it, and it surges the dark ones urgency to draw him to Shayoul ghoul.
So meanwhile, Moirane and company can have met the Amyrlin Seat and produced the story line of Aes Sedai, by all faculties required. Where she has to follow the weave of the pattern, and carry on to the Eye of The world. She can be engaged in a tyrade against the villain of that circumstance.
Where Rand shows up, in an epic centralization of their characters. Mat is unconcious by the back lash of the taint. Etc etc. the details of the conflict. Moiraine and crew are victorious, she recognizes the curse of Mat, takes him to Tarvalon. Rand is overcome by the reality of everything and takes to his course. (to what i dont remember exactly).
the end of the movie, can have Eladia, have her talent take hold of her, foretelling is it? It can be energized by the combustion of events at the Eye of the World, and lead to the further plot point of the next movie. The association of her, to what can come, can be depicted when first meeting with the Tar Valon procession at the Border Lands; as well as having first encountered Rand, in Camelyn.
Again maybe finishing with some sort of encounterance with the Aiel/chosen manipulations, via a depth, expansive cut scene.
like, queue far scope camera, honing in on a bunch of sandy brown dots, scaling over the walls of dragon mount. zooming in on the raw and war cut definitions of the Aiel.
roll credits with powerful music encapcilating the escalations of the next film.
The inbetweens, of climatic engagements, I have left out, just to get the overall loadage, of the film.
Leading into an elegant escalation of events, in one viable motion. Say, 4 movies? 5 movies?
edit: ps. dont account for my piss poor writing communication. My mind expresses stunted versions of its vision.
pps: a lot of reliance is on the heart of cinematography - soul of the earth - portrayal if you will. Bypass a lot of the massive detail volume of the books, in rightly depicting the essence of the world.
