Been giving some thought to who could be next for the OP line.
If the want to cash in on the last bit of Onigashima hype and push the characters before it's too late, here are the ones that featured between 1-65 (kaido) on the 2021 WT100 poll:
23 - kid
24 - oden
41 - x-drake
These first 3 seem feasible
47 - okiku
48 - izo
49 - hiyori
54 - otama
55 - killer
56 - ulti
These seem more unlikely, but quite honestly, if they don't do them now, they'll never get another chance.
Then you've got the top 30 pick (excluding strawhats) which could probably be made at any time:
hancock
carrot
ace
sabo
shanks
rosinante
katakuri
crocodile
marco
doflamingo
vivi
bon kurei
perona
smoker
roger
mihawk
