Deception should default to an Intelligence skill. Creating a replica that is convincing enough to fool the experts requires deep intellectual scholarly comprehension of the relevant subject matters. Likewise to weave a consistent web of lies for a confidence scheme that can survive scrutiny from professionals, requires Intelligence.
Charisma Persuasion is something different. It is a social skills check, addressing the needs and concerns of persons, after all the information is known. Intelligence Deception is about fabricating false information.
Or, for the sake of art and entertainment, Intelligence Deception is to formulate a technically convincing simulation, including writing a novel or painting an optical illusion.
For art, I always make two checks. One for technical skill, and one for viewer enjoyment. For example, a dance would be Athletics for technical, then Performance for the artistic masterpiece.
