Wouldn't that break the style of the game? Isn't it kind of odd when the player characters have 3D models as avatars while everyone else is stuck with painted ones? It's more of a soft push to have only the names displayed.
3D character models will look out of place. Avatars must be 2D that would not spoil the overall style of the game, they read must be established on the basis of established character and not be selected separately.
