i just thought i'd try out my own storyline for spider-man 4 and this is what i've got so far:
Here's a suggestion:
Dr. Connors secretly tinkers with his sample of the symbiote in combination with Lizard DNA to regrow his arm; only it works to well and becomes THE Lizard. Soon enough, J. Jonah proposes that a REAL hero capture the beast, a certain Sergei Kravenoff. Kravenoff has been making a name for himself capturing rare and powerfull animals for sport in Africa and Europe. He travels to America to (what else?) capture the elusive Spider-man. So, Kraven tracks down The Lizard through the city and finds him deep in the sewers. Meanwhile, Spidey's also looking for the Lizard so that people won't get hurt. So, we get a fight between Lizard and kraven with spidey near the end. Then, kraven gets his butt kicked and his pride won't take it so he begins to "juice up" with an old OSCORP secret formula and becomes KRAVEN THE HUNTER. Finally, the deranged Kraven and The Lizard square off against Spidey in the middle of Times Square.
Oh, and i'd put in Shocker or Electro as a minor villain early on. I like the characters, but they'd be better suited as minor characters at the moment.
I'll work on this again one day, to flesh it out a little and flex my writing muscles a little.

I personally LOVE Black Cat a.k.a. Felisha Hardy, so she'd make a great romantic interest for Spidey in a later movie. If they were to put her in a love triangle between her, Pete and Mj, that'd be great.
