But they weren't BORN into the team. They all had origin stories.

Do you think really think if Fox released a Wolverine/Jean/Cyclops/Storm solo movie in 2000s, those films would have been so successful and it would have led to X-Men team-up? Comic-book movies weren't even that accessible in the early 2000s. We only had Superman/Batman movies during the 80s/90s. The others weren't so successful. Blade had its success in 1998 but like as if people viewed that a comic-book film.
X-Men aren't exactly similar to the Avengers and the Justice League. Even in the comics, they aren't.
Dude, you yourself suggested in an earlier post that the X Men film with origin stories that came before could have been a big deal... so yes, I do think those films would have been successful for building up a shared universe.
