Combine both "3D in the player and 2D in the gui" and "dynamic textures (override)"

I already got a weapon to visually render a 3D model in the player (third person) and display a 2D texture in the gui (inventory, item frame, dropped).

I also got another item to dynamically change its texture based on nbt data with "CustomModelData" and "override".

However, to get a great part of my mod to work as intended, I would need to combine both functionalities. So I'd like to know if it would be possible to have a weapon render 3D in the player and 2D in the gui, and dynamically change its textures (2D and 3D) based on nbt data using override.

I would appreciate any help. Thanks 😊
