part 3 could have been the lizard. think about it. it would totally not be a step down. Remember the Lizard tried to turn the human race into lizards. Imagine this spider-man has to get to this location to stop Conners from turning all of New York into a bunch of lizards. Conners has created hundreds of huge mutated lizards about the size of a boxer dog. they are fast, agile, they can climb walls, and they can jump high. And they are stopping peter from getting where he needs to be. they are chasing him through New York jumping off of walls and rooftops to get to spider-man. Spider-Man is just swarmed with these things all over his body, as he tries to continue webswinging to get where he needs to be in order to stop Conners from turning all of New York into lizards like himself. the whole time spider-man is trying not to drop the serum to cure conners. you could bring Ock back. have possibly an awesome fight between him and the lizard and countless lizards. Harry/Green Goblin could have sent Ock to capture the lizard, because he's planning something evil himself. in the end the only way to shut down the machine which conners built is to self destruct it from the inside killing whoever stops it. MJ "don't" PEte "I have to" MJ "you'll die" pete "I know" Pete "i love you good bye" pete jumps in but while he's falling green goblin pins him up against a wall. "sleep spider" as he sprays him with the samd gas his father used in the first one. spider-man lays there unable to move. Harry rips his mask off. MJ "what are you going to do?" Harry "what needs to be done" then Harry makes the sacrifice to stop the machine. Harry could have been behind the whole thing. He knew the way to defeat spider-man would be to make him kill himself in order to save New York. but in the end he couldn't go through with it. It's got drama, awesome fights, an emotional pull with spidey fighting his teacher he cares about. a dramatic moment between MJ and pete.
