OP's anime is (like any other anime basically) a glorified 20 minute commercial for people to buy merchandise of that franchise, so right now it is outweighing its costs (reportedly around $90,000 USD per episode, but I don't have a date for when this was reported, so it might be more due to inflation and stuff), so basically every episode costs $90,000 USD to make, and in sales of figures, games, licensing fees, etc that cost is recovered at the very least.
I don't see how a remake would damage the brand, since it could bring new viewers (Maybe kids, which should be the target audience, but One Piece isn't really read that much by kids in Japan nowadays from some data we have seen), so yeah I'm guessing it would be good to bring new viewers, plus I doubt it would lose its normal viewers.. But then again I'm just a random dude posting on a forum haha so I might be completely wrong.
