It's possible. I would say that though, since I really want this to happen. If you're familiar with the Kickstarter rewards available, you'll notice a reward called "s3 world telecom" which not only allows you to call old friends/relatives from Yokosuka but it also gives you access to flashback scenes.
Maybe during your conversation with Gui Zhang, they talk about Chai and Ryo's boat journey. Cue Ryo having a flashback and boom! We get to live out Ryo's boat journey via a flashback.
That's a really good way to weave a playable chapter 2 into the story line.
