Don't take this the wrong way, but if they make his death also happen in-universe I really hope they find someone good otherwise it might end up being Far From Home-2 (talking about similar story beats here, like the person not thinking they are worthy of the mantle, etc). While M'Baku could be great (I like Duke as an actor), Shuri would make more sense. Still, even though I absolutely loathe them, I'd rather see a flashback movie.
They fucked up so bad killing Killmonger, goddamnit.
