I suggest that you reach out to the AEM support group to see if there is a special way to do that however the first idea that came to my mind was to publish a slightly different new one like: "Hackathon-XF-V2" and that should do it.
If this satisfies your query please like, mark as helpful and mark as answer. Otherwise lets keep the conversation going. Hope you have a wonderful day.
