The term 'Creator Killer' might be WAY too easily confused with Author Existence Failure, Rage Against the Author or The Fourth Wall Will Not Protect You, where the creator can be literally killed by his or her work.
With that in mind, I suggest the name of the trope be changed. My suggested new title is Creator-Derailing Project (a title I've already used in The True Tropes, a fork of All The Tropes). It's a title that's similar to the similar trope Star-Derailing Role, and is generally less confusing.
