Nah, I doubt it. Would make a good fanfic though
Depends on how it is done. As a writer, I notice a lot of works centered around a canon character’s sibling oc, the original character can be overpowered, cliche, a Mary Sue/Gary Lou, or is an anti-sue. The character needs to be balanced, likable, and relatable. If the author chooses to implement hard topics, they must approach tough topics with sensitivity.
I would love to see someone give it a go and do their best!
