While using Ben, and specifically a cloned Ben, certainly opens up the possibility of further clones (and this hasn't escaped me for potential narrative spools down the line), we run the risk of not distinguishing the characters enough for comfort within the same game, and with Silk already accepted, overloading the game with Spider-People regardless. 

But far be it from me to stifle your flair. Ben isn't accepted and I can't act like the arbiter of Spider-Man even if he is.
