If things are like they are now (there doesn’t appear to be any negative side-effects for the various Venom-varients that aren’t self or Hellmark caused), could there be an AU where Peter keeps the symbiote? I know there are What-Ifs, but considering Eddie, Flash, Cletus, Lee, and Andi all used symbiotes for extended periods of time without being aged or reduced to bones, I’m guessing those aren’t in play anymore.
I specify an AU, as it seems 616 Peter has too much of a negative attitude towards symbiotes to consider that here.
As an added question, if you did have Peter keep the symbiote, would you still have Venom? How would you include him?
