Certainly looks interesting. But why would you want to imitate other writers’ styles, except for pure novelty’s sake? You could also train an AI to imitate yourself, given enough content, but why would you? I’m not sure I fully understand the motivation.
Non-AI writers, including professionals, imitate other writers' styles all the time, whether that's specific writers or a general genre. For example, the Dresden Files series started out as an intentional homage/parody of potboiled detective works except with all the urban magic stuff added in, and retained much of that style over time, like the intentionally overdramatic internal narration.
