I would recommend 'A New Beginning for Kaneki and Hide' which can be found on Archive of Our Own. It has a unique take on their relationship, exploring what could happen if Hide had a more active role in Kaneki's transformation journey. It's full of emotional moments and great dialogue.
Well, you can try searching on fanfic platforms like Archive of Our Own. Look for tags related to 'kaneki x kaneki' and exclude any tags that might indicate lemon or adult content. There might be some great platonic or friendship - centered fanfics about these two characters.
Often, there are themes of protection and support. Given the unusual situation of mpreg, Hide might be portrayed as being very protective of Kaneki. And also, themes related to the acceptance within the Tokyo Ghoul world or their own small community could be present. Since it's an unconventional concept, how other characters react to it can be an important part of the story. Additionally, themes of love and sacrifice might be emphasized as they face difficulties together because of the mpreg situation.
One common theme is friendship. Often, the stories start with a simple acquaintance that grows into a deep and meaningful friendship. For example, they might bond over shared hardships or a common goal. Another theme is loyalty. Kaneki and the male reader usually show great loyalty to each other, standing by one another in dangerous situations.
A common theme is the exploration of their dual identities. Given that they are the same character in different states, fanfics might delve into how they interact with this shared yet distinct self - awareness. Another theme could be self - discovery, as they come to terms with who they are both individually and in relation to each other.

Keep in mind that the availability might vary depending on the popularity of this particular pairing and concept within the fandom.
One possible scenario in a Naruto - Kaneki fanfiction could be that Kaneki somehow ends up in the Naruto world. Maybe through a strange portal or some sort of jutsu gone wrong. He might initially struggle to adapt to the different environment and the presence of chakra. But his own unique kagune abilities could be seen as a strange new form of power in the Naruto universe.
One can expect a lot of emotional turmoil. Kaneki is often conflicted, and Tsukiyama has his own quirks. The 'lemon' part might bring out their more vulnerable sides in a relationship. It could be a story of two souls finding solace in each other.

Another plot could revolve around how they deal with the reactions of the other characters. Some might be accepting, while others could be horrified or even try to harm Kaneki.
