Quick thought (i know i havent been on here for ages). Might pop up now and again to drop a quick thought 😁.
As most of us know Reverie is drawing near, admiral Fujitora wishes to abolish the Shichibukai system. That sparked a thought of how exactly would they do that, would they just publish it in the newspaper, would it be similar to how they invite you to become a Warlord (sending a carrier bat or seagull - something like that ) or the way i believe is more Logical, considering first and foremost they are pirates. I think a meeting will be held which will call on all of the Shichibukai, like we've seen them before, and they will be informed that the system they are being protected by is currently no more and the marines will then TRY to apprehend them all.
Obviously this is no easy task and i doubt they will be able to pull it off but in my opinion it would make alot of sense.
The problem with this prediction is as most of you know alot of the Shichibukai are quite stubborn and would most likely decline going, as they've done in the past, but anyway just my thoughts, how do you think they would carry it out??
