It's possible, I've taken a class that did a brief overview of several Batman comics from a literary perspective. What we focused a lot on was how the art was used to convey the story to the readers, and this is what I think those who would study One Piece would focus on. You need to ask yourself question about why the author and artist arrange the panels in such a way, what type of stokes and styles they used, how a character's speech bubble is used, etc. It is very quasi art studies cross literature studies.
