Luffy will, solely so we get Two Piece a few years after OP ends.
Zoro will, and they’ll be just as grumpy and directionless as their dad.
Nami will, mostly to sculpt them into superior thieves.
Usopp won’t, he doesn’t know how it’s done.
Sanji won’t, kids would cramp his style too much.
Chopper is still biologically an animal.
Robin and Franky will have children with each other, and the Frobin Pirates will usurp the Straw Hats as the greatest crew on the seas.
Brook is a living skeleton.
Jinbe won’t if he hasn’t already.
