If somehow One Piece live-action reaches beyond Whole-cake island, how do you think they're going to handle Sanji's past with his family?

We mostly agreed that the LA crew growing up along the journey is acceptable, but how about the kid actors?

Luffy's kid actor gets a pass because the Additional flashbacks are after he got his fruit.
But Sanji's flashbacks happened before he met Zedd

(Are they going for a more younger actor for it? I guess it's Netflix, this show might just get cancelled before we reach Jaya)
