I don't think Momo will get de-aged tbh. I mean, it's sad that he doesn't get his childhood, but technically he should've been 28 anyways. Plus someone's gotta defend Wano.
Overall Bonney's power isn't something I see on the crew, unless there's anything extra to it, she's basically a one trick pony, all her fighting scenes will be same as we've just seen in the latest chapter.
I agree on the rest points though, both for SH and Revos. Personally I think she'd fit with the Revos better, since to me she's kinda female Luffy, but if she does join the crew for some reason, I will be fine with it (although my personal choice out of all supernovas would be Trafalgar Law, of a supernova had to join).
Yeah,
@Rambles, when can we start collecting on those bets? :D
