I was also thinking during a recent re-watch that it would have been interesting to keep Miles' daughter as an older girl when she came through that time portal instead of bringing her back as her normal age. It would have been interesting to see if she were to adapt and actually stay aboard the station, eventually she could have been a love interest for Jake or even Nog.
I think that would have been great!
Then Sisko would would have to decide which one pisses him off more, Jake with the Dabo woman or Jake with the cave woman. That's what you get Sisko when you move an impressionable boy out to frontier space
