Yeah, FF was Stan's response after seeing the success of a superhero team in general. But they're not really Marvel's version of the Justice League. The Avengers is the all-star team showing the inter-connected-ness, and if they were drawing inspiration from DC's Justice League for things like the Fantastic Four, I'm pretty sure they'd be drawing inspiration from it for something even more similar.
