Purely hypothetical. Of course.

Let’s say I have a main character who would benefit from character development the most. A natural process that happens overtime with the characters most in need of it typically being the points of view throughout the book(s), where having that PoV allows for an easier time developing the character.

Now, let’s say I didn’t do that and instead I wanted to try developing their character (who again, needs it the most) through the perspectives of the other main characters. The character in question would have a slow, gradual development, but it would be conceivable with every book, from the first to the last, until it finally comes to an end along with the narrative. So the reader would come to understand this character more with each PoV they experience, in addition to seeing those PoV characters’ thoughts and opinions of said character change over time.

I feel like this approach could be interesting, but I’m curious to see what others think.
