I suspect that GJC would have taken a look at the quality of the kid, and if he was lacking, might still have picked Octavian for his heir.Pompey the Great would have been married to one of Julius Caesar’s nieces instead to cement the Triumvirate for starters.

OTOH, maybe the kid's good, who knows. Grooming an actual son for his replacement might lead to earlier and more plausible claims he wanted to be king. That could lead to an earlier assassination attempt.
What if Caesar's son and Octavian split the throne, going along this route?
