While I understand the context, I'm not sure I can be on board with the cover story featuring a bunch of children and being called "the next generation of CP, in training!"
Luffy has already invoked for the help of 4 of his missing crewmates, being sanji, franky, nami and chopper. Makes me think of when he told arlong that he is strong only thanks to his crew, who help him with things he is unable to do. This kind of continuation is what makes one piece so special
Ps @AkivaNugent read chapter 0, there is basically the same scene but 20 years ago and with the current cp9 formation training as kids
