Such examples of "appearing to have internal reactions but not actually having them" already exist in the world so I'm unsure why you're even asking the question. It seems like some sort of midwit positivist low IQ nonsense of "If I can't tell the difference, there is no difference!" which is obviously retarded and one of the reasons why logical positivists are a joke and the philosophy is dead.
Not saying this about you at all, I am not calling you a positivist so please don't be offended.
