I don't see this as a more suitable term; I had to check the definition of "confabulate" and the first hit in the macOS dictionary is "formal; engage in conversation" and the second is "psychiatry; fabricate imaginary experiences". The fact I had to look it up to make sure, and that it isn't the primary definition, makes this a bad alternative to a well understood word which has already become established.
