Good, even great ideas there. While Kraven is back to being dead thanks to the Hunted saga that closed out the first year of Nick Spencer's Amazing Spider-Man, he does have a clone son out there who's taken up his name and mantle, so he could easily show up as an antagonist for Black Panther. I particularly like your assessments of Killmonger and Klaw as well. Moses Magnum as a corrupt weapons manufacturer and dealer with an interest in appropriating Wakandan technology (and vibranium) to make deadlier and more powerful weapons that he can turn an even bigger profit from . . . that would be pretty inspired, too.
