Joystick would definitely be great to see again, could cast her as an even more amoral Black Cat in juxtaposition with Ben as Spider-Man. As for the larger point about not creating new villains or at least dredging up more obscure preexisting villains, a lot of creatives in the industry don't want to basically give away their best and/or most original ideas when they know the Big Two (still) won't compensate them fairly, especially when those ideas get incorporated into multibillion-dollar mass media franchises.
