I believe the AU wiki was already on it the moment Deltarune was released; especially since the game was the official AU of Undertale and vice versa.

Though I'm thinking about an fusion AU of Undertale and Deltarune where: 1.) Chara named Kris (or Kris in Chara's place), and became one of Gaster's assistants. 2.) The experiment not only scatter the royal scientist across space time but unleashed portions of the Dark world across the Underground. 3.) Kris became part of a team to clean up the mess that they helped create.

I'm currently ironing out the details, but that's the basic premise.
