In a fanfiction scenario, perhaps Hermione has a research project and enlists the help of Bill, Charlie, and Harry. Bill could offer insights from his travels, Charlie might contribute with his expertise on dragons as it relates to the research, and Harry would be there for moral support and to offer his unique perspective as the Boy Who Lived. It could be a story of friendship and cooperation in the magical community.
One possible fanfiction could be about Bill Weasley meeting his mate during his work at Gringotts. Maybe she is a half - blood witch who comes in to do some business.
