All i'm gonna say is that there is a major difference between Momonosuke and Vivi, and that is, everyone doesn't wanna capture Vivi. No one is after her, she's safe in Alabasta (or anywhere where there isn't already danger present, for that matter). Momonosuke is constantly being wanted and in constant danger no matter where he goes. Unless he is permanently put in an undiscoverable, unpenatrable hiding spot, he will always be on the move. Which means that in some way shape or form he will probably have to join the straw hats for protection (I mean, who else besides the straw hats, or anyone associated with them would protect Momonosuke on a long-term basis). I highly doubt he will just end up living peacefully in Wano before the end of the series.
