So, story-wise, there is a chance that the twin will get into some sort of trouble like the twin in FF4 (they petrified themselves to stop advancing walls of doom), rendering them absent for some time.
Then you know in FF4, there is this old man named Tellah. He is a Sage. He died due to exceed his MP pool to cast the powerful spell Meteor. It is possible that Alphinaud, who becomes a Sage will exhaust himself trying to cast some grand spells, or simply run out of juice when trying to shield WoL from a big attack.
Whether he dies or not, it is hard to tell. But if SE want to kill off one of the twin, Alisae seems to be more likely the one to go. Out of the twin, she is more reckless, hot-headed, so more prone for being killed in battle. Alphinaud is a more helpful when it comes to rebuilding the world post-EW, and he will just continue Alisae's treatment for the tempered.
Another candidate that have a higher risk of dying is Thancred. His story is already completed back in ShB, and he has someone continuing his legacy despite she is in a different world. His liability to use magic and having to rely on other people's charging his cartridges may become a fatal weakness.
Einstein is a candidate too, but he may get away as a rule-of-cool character.
In short, the battle-type characters are more prone to get themself killed/sacrificed, while the scholar-type characters are more likely alive for world rebuilding.
Out of all characters, the one I don't mind dying is Lyse. I don't feel any attachment to her since her poorly-written story back in Stormblood. It feels cringy everytime she appears on the screen.
