Makes sense. Perhaps Chapel and Spock break off, Chapel marries Korby. The grief for Korby turns SNW Chapel into TOS Chapel. There's room for the dealings with Leila Kalomi.Chapel would have to be at minimum 90 for this to be the case. Not that there's anything wrong with that mind you, but it just seems odd then that she and Spock would wait that long.
Sometime during or after the TOS movie era, Spock marries Chapel. Do they have children?
And then Picard attends Spock's and Saavik's wedding in the early 24th.
