In a story called "Two More Years", Spider-man will make a deal that will get his Soul sent over to DC Comics in Two years. There, he'll have to kill the BIG 7 Justice league members, which he'll be told make the avengers look like light weights. Hearing that, Spider-man will take the prep very seriously and upgrade himself in whatever way possible (magic, new powers, stealing stuff from people and trying to not get it taken back, etc. The one thing Spider-man can't do is ask/borrow things from people. He's got to be a villain about it...
After the prep-time is over, Spider-man Aunt is saved and he gets sent over to DC. Over in DC, none of the heroes know Spider-man will be coming for them. Basically, he can take however long he wants and try to blend in all with the end goal of killing the justice league. Additionally, to give Spider-man a fighting chance, Peter is immune to all Telepathy or psychic probing/attacks.
Right then, so can Spider-man do it?????
