If they're casting a late 20s-early 30s male, essentially someone S1 Emma's age, I don't think the kid can be Robin. But the theory is intriguing.

Henry is roughly 13 years older than her. They didn't give the new male a specific age but they are saying the kid is 10 years old. So if the man is an older Henry, he must be ~23 years old - which is probably not what they're going for if they want "late 20s-early 30s." If it's just any child with some connection to Henry, it'd have to be a child born in the next 3-5 years.
