Honestly, I think the other two are far more likely. Silk is a more derivative character. Meanwhile, there are places you can go with a Silver Sable story, with her being an international mercenary, that’ll make her her own character away from Spider-Man. I think Black Cat is more difficult to do. But if you do it like a heist movie, I think you can have her character get through a stand-alone or two. But I think eventually you will have her interact with Spider-Man and that is also true of Silver Sable.
