On the other hand, if some of the fanfiction was a bit too outlandish or inappropriate, it could make things a bit awkward. Hawkeye might feel embarrassed, and the other Avengers might not know how to react. But they'd probably try to smooth things over and remind Hawkeye that it's just the creativity of the fans and not a true representation. They'd still support him as a teammate.
There are a few pirate novels with Hawkeye as the main character that I can recommend. Among them were One Piece: Demon Farm, One Piece: Supreme Swordsmanship, and New Pirate: Hawkeye Is My Defeat. These novels were all light novels or doujinshi novels with interesting plots. However, due to the limited search results provided, there might be other pirate novels with Hawkeye as the main character that were not mentioned.
