Question About Island-Specific Cosmetic Purchases Under Rule 4.4.6

Hi, I’m developing a UEFN island where the player is represented during gameplay by a custom non-human mesh rather than their visible Fortnite character. I’m considering offering optional V-Bucks purchases that only change the visual material/appearance of that custom mesh, with no gameplay advantage and no effect on the player’s Fortnite Outfit/Skin or locker cosmetics.

Would this kind of island-specific visual customization be permitted as an in-island transaction, or would it be classified as an Outfit / overall character appearance under Rule 4.4.6?

I want to make sure I’m interpreting the rule correctly before implementing any paid cosmetic options.

Thanks!
