Ehh maybe after he meets Luffy I can see it tbh. No doubt he'll be wanked in defeat too
The details change, but one of my longest held theories is that Shanks will die on Lodestar at the hands of Blackbeard.
I think he and Luffy will have a brief reunion before he makes it clear he's in it to win it, and of course Luffy would accept nothing less.
Their crews will fight, but I think most of them will kind of hold back, kinda similar to the Roger Pirates VS WB Pirates in the Wano flashback, with really only the captains and respective wings getting emphasised.
After some time, when both have expended significant energy, Blackbeard shows up - fresh off killing Imu and stealing his powers - to kill them both, but succeeding only in killing Shanks after the latter ensures a defeated Luffy's escape, with the revelation he believed he was not the "Child of Destiny" but the person meant to guide them. As he dies, it'll be clear he would've lost regardless, but his feat in protecting Luffy will involve the best CoC feat to date, even superior to Joyboy's dormant Haki (which I would not assume was the full extent of Joyboy's power).
I have many different iterations of this going down with, some including their respective allies, and some that don't, but invariably, I think Lodestar is basically where Blackbeard puts the stamp on his villainy.
I also think it's now possible he steals Shanks' sword.
Hell, for all we know, Gryphorn once belonged to Xebec, and recognising it is what drew BB/Xebec to attack Shanks.
Whichever way it goes down,
Shanks must die. That's his role in the story. Otherwise, where's the tension?
