See part about the part about repudiation in my original comment.
Come to think of it, deepfaking your face onto someone else's body is probably the hard way. It's way easier to mutilate (ie. making subtle but plausible edits) a real nude of yourself so you can repudiate it later.
If you really need to convince some small number of people that the pictures are fake, you can reveal yourself to them in private.
But I can't think of many scenarios in which either of these approaches leave you better off than just having real nudes made public in the first place.
That doesn't seem too hard. The edits can be made to places that you can "safely" show to people (eg. upper arm or belly area). You can also make yourself look thinner/fatter/more muscular (body only, not face) so your friends/family will immediately recognize it's not you.
