My brain, grabbing me like a cartoon kitten: Take Monster Prom, a series specifically meant to be a silly parody of countless tropes and stories, and turn it into an insane dark modern fantasy anime where Oz is the reincarnation of an Edlritch Primordial Deity, Vicky is a Frankensteinien Cyborg who can control lightning, Brian is a Taoist Cultivator who got reanimated by his master after death and regained sentience and Amira is a primal force of chaos with enough firepower to beat Damien who can channel the combined power of all of Hell.
I swapped the color palettes of the main 4 in monster prom! My personal faves are Amira and Vicky <3 (Characters not mine obviously. I just swapped the palettes)
