At the risk of belaboring the point, we cannot know for a certainty what Miura planned next. We are only taking on good faith that Mori has a rough outline of the major plot points.
If I had to bet on it, I would say that yes Griffith did kidnap Casca in Miura's vision. If Griffith simply teleported away after the big reveal, it would be somewhat... anticlimactic? While kidnapping Casca only solves half the equation when it comes to the Boy in the Moonlight's longing for his parents, one parent is better than none. We are also presuming that Griffith has prescience that the boy needs both parents when this entire scenario is a wildcard that is outside of his control. Casca's kidnapping also presents us with an outsider's POV in Falconia in place of Rickert.
Of course, do I think that everything unfolded as depicted by Studio Gaga with the island unceremoniously collapsing and new players noping out? Hell nah. There had to be an catalyst for the party to leave Elfhelm since it was an oasis for everyone, but there was clearly unfinished business there and I think we had some exposition episodes lined up. Since Studio Gaga didn't know any of this or cba with it, they skipped to the island's destruction.
