I'd love to have Picard visit the Academy where Miles is still teaching and is now the head of the Engineering Dept., and Keiko has joined him as the head of the Xeno-Botany Dept. where she was also given the opportunity to redesign the Academy grounds to reflect all the worlds of the Federation.
Now that Boothby has passed and the O'Briens are empty-nesters with Molly and Yoshi and any other kids off doing their own things, Keiko and Miles walk the grounds she designed every day to check on things and have a picnic lunch. Together, they have become the de facto new Boothby for the cadets, dispensing homespun wisdom, advice, and anecdotes, since the new groundskeeper has a bit of a standoffish personality.
Talking to the cadets also allows them to live vicariously as if they were hanging out with their kids. They still talk and visit with them as often as they can, but with their distant postings it can be difficult, so talking with the cadets helps them cope with missing their kids.
