I would love to see a retro series where Spider-Man teams up with Arthur Stacy, Gwen Stacy's uncle. The series could develop the Stacy family background and showcase the mental prowess of a private investigator. Spider-Man could be called upon to assist Stacy with information that would confirm his sleuthing. Of course there would be cameo appearances by some of Spidey's more notorious villains. It would be a hoot!
