I kind of like that idea. It would've been interesting if he had spent those twenty or so years searching for his children (somehow he learns he has twins maybe). He finally comes in contact with Luke and Leia but doesn't realize they're his children at first. He eventually finds out they're the children he's been searching for all those years. He could also search for them but can't find them and eventually loses hope. Luke and Leia finally meet them for the first time and he eventually realizes they're his children he was searching for who he lost hope in finding.



He could also think he had one child and find either Luke or Leia and raise him or her. In some ways, I think it would be more interesting if he had found and raised Leia because he had wanted a daughter and she's so much like her father that she's more likely to grow up to be like him. Luke would probably grow up being his father's "moral compass". Then he finds the other twin and finds out he/she is his child too.
