Didn't they do Ultimate Jessica Drew as well?

With this Vulture, my guess is aside from the cartoon inspiration (which others have mentioned) they may have just wanted a comic Vulture that is vaguely similar to the one in the movie for more casual buyers. With the helmet and back-mounted wings (as opposed to them being attached to his arms) the toy looks almost like an the middleground between the classic and MCU designs.
