Something like that would probably require a whole new script to implement, and Fandom doesn't like when wikis make custom scripts. Not to mention finding someone with the relevant skills who is willing to do it for free could be a challenge.

It might be possible to develop such a feature for one's personal JS, but you'd have to ask around MediaWiki coding circles to see if such a thing has been developed. In the mean time we have author categories for authors with a lot of stories.
