This is interesting! I actually had a similar idea of using that scene awhile back, but for a different purpose.

I had this idea that maybe the bundle that woman is carrying is actually a baby, and you could add baby crying sound effects to that scene. The next time we see Finn, when the officer puts him in formation, you could alter his line to say, “The children are on board, now stay here.”

I like the idea of Finn realizing he is perpetuating the cycle. He was kidnapped as a child, and now he is kidnapping more children. Finn and Rose help give the children of Canto Bight hope for a better future in TLJ, and we get some mentions of more children harvesting in TROS, so it’d be interesting if somehow that arc came full circle by the end of the trilogy.
