1.) "To de-censor JAV videos"
yeap, someone already created this software a couple years back. I admittedly looked into it but never tried it myself. I don't recall the name offhand but it does use some AI but it is not as advanced as the face swapping process that we have today. Here is the rub - you would really need to build this model from scratch by training models of pussies from all angles and then training the model with various mosaics of those very same pussies. So you could not really use Jav videos for the training... but yes it can be done properly and quite convincingly with some time and dedication.
2.) "Enhance" models - or "un-enhance them" - yes to all of this, but the more that the AI has to draw, the longer it is going to take and the less realism you will achieve.
3.) "Hiring traditional models / celebs for their likeness without making them do porn directly" - not so sure about that, but I do think that models would be more willing to do porn if they could obscure their face with a 'fake' face. Not sure if you are familiar with the concept of AI influencer, but it is possible to create a completely fake AI person. So the model body is very real but she gets to hide her face and keep her anonymity by keeping a fake (and still lifelike and beautiful) face that could look like her without actually being her.
4.) "Putting the viewer into the scene more directly" - lol I did this for fun in a 2D scene so yeah its completely doable already.
