Post-Wano/Onigashima was brought up, and there is a chance there I think, as well.
As far as being sideline completely, I don't think so. There are a lot of characters in Wano, but I just can't help the feeling that we will be seeing a lot of Drake during Wano and then maybe not again until down the line with the Marines depending where Oda decides to go with Drake's character.
As far as outshining others many other important characters, probably not, but still a sizable role overall once Wano is said and done with.
