As far as I know Viper is a mutant, not a mutate.

And even if Spider-Man and the Fantastic Four are mutates, they still wouldn't fit into FOX's MCU, even less perfectly.

Just because they have modified genes (and not even for the same reason) doesn't mean they will fit. It has to be taken to account the realtion of those franchises in the comics, a medium in which the X-Men and the Fantastic Four have barely crossed-over, almost the same goes with Spider-Man/X-Men.

On the other hand, the Fantastic Four and the Avenger have had a lot of adventures together.
