That just wouldn't work. Marvel publishing would fall apart without Spider-Man and even though X-Men had lean years between House of M and Hickman, it never got outright canceled unlike Fantastic Four.
Likewise you would have to age-up the Fantastic Four and the Avengers and make them five years older. That might not make much of a difference since those characters have always been coded as being middle-aged for the most part, but that also means Franklin and Valeria Richards (unless one or both are snapped) would age up too. It also means Johnny Storm, only slightly older than Peter, becomes much older than him.
So logistically in terms of continuity it would create a lot of problems. What made it work in the movies was that actors were aging out of the roles and this allowed for a grand hurrah for them to bow out and a new altered status-quo.
