Until we get Ray & Gaban's bounties we cant be sure. If Jinbe is in the 2B range and Zoro-Sanji 3.5B+ range its quite strange because as of now there was never a crew with so many high bounties. When we learn Roger Pirates bounties we will know for sure.
I dont think thats even needed when after reading the story for so long
the crew isnt awfully similar to roger's at all
No vice captain, No first mate
so while rayleigh was far more relevant in roger's crew than gaban, zoro and sanji have equally important roles as far as the crew is concerned . The opponents they fight will continue to be not that far apart both in threat , reputation and bounty and their rewards would echo that.
luffy
two wings who are his n2 and n3
that will continue . zoro prob surpasses mihawk's bounty and sanji is easily around the 3 bil mark .
