Drift net fishing

I have created a custom model for a drift net. I want it to inherit the fishing rod but i don't want to replace ALL fishing rods. I am making a datapack along side this to add a recipe for the net which will add a custom_model_data tag. I have gotten the model to work but it replaces all fishing rods. When I however add the "override" section in the json file for the fishing_rod.json it just completely messes it up and everything gets missing model and texture
