Is it possible to change the position of a item model depending on the player model in JSON

Is it possible to change the position of a item model, depending on the player model, in JSON?  So, like, if you wanted to render an item on someone's wrist, is there a way of knowing what player model that person has (IN JSON). If there is no way, tell me how I should do it

You can change position in which an item is rendered based on it which slot is it and whether it is viewed in first person or thidr preson. That's it. JSON can't determine if player has a different model. By the way, why do you want to change player model?

Not in vanilla JSON, but the code to do it would be pretty simple, and you could also add an API allowing other people to use JSON
