What do you think about a special side story with different choices after the main plot ends?

Brothers, lately a lot of readers have said this stretch has been frustrating to read, but if I go back and revise it from the beginning, not only would the workload be enormous, it would also be easy to create logical problems.

But if I write a new volume of side stories afterward, there won't be that issue. I've suddenly had an idea: after the main plot ends, I could write a side-story instance similar to a parallel timeline with different choices.

It would probably continue the usual harem formula. Starting from the Spirit Road arc, the protagonist's dear son leaves home to gain experience and keeps running into all sorts of plots involving his little mothers. Luo Li, Ling Xi, and so on could all be included.

It feels like it could be pretty promising. Everyone, vote on it—should I write a side story like this?
