There's always the late Mike Wieringo's Thing:
I'd love to see something like that with Ben Grimm's jaw which slightly juts out.
In fact, his FF would be a great template to have for the movie. His designs look very Disney-ish, and the whole "Imaginauts" storyline (written by Mark Waid) had a story about the comics trying to update the FF for modern audiences but their designs failing miserably. So they sent a representative to spend a week with the team to see what makes them tick. And what he had to report back is that you need to make them MORE like the classic FF everyone knows, rather than less like them.
So Trank and Fox obviously never read that story or ignored it, because they did the very thing that was discussed in that comic, and they failed just as predicted.
Ben Grimm needs to be the heart of the team. He was never remotely like that in Fant4stic.
He would also be fantastic if he were in Infinity War. He was great in Secret Wars, even despite changing back and forth between his human and rocky versions.
Audiences need to love him like they do for Rocket and Groot.
