API method to get a player's current model

[Olfi01]

I've looked through the Wiki and couldn't find a way to retrieve a player's current model. Is this not possible? Could it be added?
I would like to be able to retrieve a player's current model to be able to temporarily apply it to others.
I would also be okay with it if a player could block this functionality clientside to avoid the possibility of obtaining players' custom models without their consent.
