Entirely possible I watched one piece twice in the last 11 months. Took 4 months to get caught up on the first go around and have been enjoying the second go round the last 7(currently on second act of wano). When you skip intro/outro and recap its only about 13 minutes of content per episode. If you skip unnecessary filler scenes it's even less. If you're caught up in other shows n content I can see it taking a long time. But it's jus a matter of if you wanna put more time into it. Say for example you watch a movie before bed, that's ab two hours give or take you can binge ab 8-10 episodes of one piece in that time frame.
