Is it really too many? It's just static recoloring. You're not actually changing the sprites or their characterization or their hairstyles, etc... like it's not a major overhaul. It's just a dice roll for hair color, eye color, and accessory coloration of the outfit that bases itself on the aforementioned.
Too many variables is more like the character's history, their supports, their figure, their default class (and sprite outfit), their hairstyle, etc... all changes to match the pairing. THAT's overkill.
All I'm asking for is a fun little color fusion. ChromxCordelia? Hypothetically, obviously. Severa? Maybe she gets blue hair, maybe she gets red hair, or maybe purple? Maybe she gets blue eyes, maybe she gets red eyes, maybe she gets purple eyes? Then depending on which two colors those roll as, her shield and little bowtie will roll to match one (or both) of those.
That's literally it. It's such a basic concept, and they chose the most half-baked route. Kind of like having ugly, 3D battle models with no feet.
