Other mistake: Spider-Man and Detective Lee both comment on the skull on the Punisher's shirt when they first see him. However, the Punisher is wearing body armor that covers most of his chest and abdomen in this scene, so there's no way they would know that he has a skull on his shirt.
Answer: Yes. Many things that would have been in the sixth season would have had Norman Osborne returning from limbo and reclaiming the title of the Green Goblin, Richard Fisk, the son of "The Kingpin" Wilson Fisk would return as a crime lord known as "The Rose", Ghost Rider would have appeared to help Spider-Man stop Dormammu from returning to Earth and Madame Web and Spider-Man would rescue Mary Jane from limbo.
