If I had to deal with another retcon, fine. It's in service to the films not the other way around even if the films tend to adapt stuff from the extended lore.
That all being said you could still have 1718 kind of work with a name change or they just happened to have the same name given Hunting Grounds does have a flintlock trophy. So unlike the situation with Weyland you could have both still work. More than one Predator has a flintlock trophy and while it might not be Greyback anymore, Golden Angel could be its own character now having encountered his own Adolini. People can have the same name, it's just not the same Adolini as the one Greyback encounters. Alternatively for any reprint they could change the name to fit in whatever canon they go for.
We could easily have Adolini the pirate, and Adolini whatever he is if he's in Prey.
