I like all of this, though I would also throw in the much-hinted rise of Mictlan, the Aztec underworld, from Kaine's time as Scarlet Spider and Aracely's guardian. Could even have Mictlan forcing Ben to act as its champion in the same way Kaine acts as Aracely's champion, a form of punishment for tampering in the realm of life and death with the "reanimates" he created as the Jackal. Speaking of, an ongoing plot thread could be Ben (and Kaine) tracking the surviving "reanimates" and taking down the ones who squandered the "second chance" they got by reverting to criminality, which would force Ben to examine his responsibility for unleashing them upon the world and what he's been doing with his own second chance at life.
