This is not a very useful mod, it's just a demonstration of using the PlayerModel frame for use on other units.

The model is animated and rotatable. It's nothing clever or new, just a copy of CharacterModelFrame from PaperDollFrame.xml, with a SetUnit applied on PLAYER_TARGET_CHANGED.
A UI could use this to replace character portraits with models, or like the above UI put a model of the player and model of target side by side.
