Leia's and Han's son Ben does take after his grandfather, not as a Jedi but as the galaxy's best pilot.
Shara's and Kes' son Poe is the new rising star amongst Luke's pupils until he turns dark and kills all of them.

I'd love if character-wise Poe and Ben stayed the way they are in the movie, so Ben is quick-tempered and awkward while Poe is charming and snarky.
