Model Display Json: 'Riding Entity' Offset / Scale / Rotation

"display": {
        "head": {
            "translation": [0.5, -60, -0.5],
            "scale": [1.75, 2.5, 1.75]
        }
    }
Is a current example of how we can offset/scale a model on an entity's head in its JSON file.

I suggest adding another option on top of the current ones. 'Riding Entity'. The ability to scale, rotate, and offset a model based on whether or not it's riding an entity would be invaluable. This would be a welcome addition for creator's in Minecraft, especially for ItemDisplay entities. One example is a simple yet powerful way to have complex visuals on a player with low cost on resources, think of 'power word: shield' from a very popular MMO. Thanks.
