Java/Bedrock Cross-play Custom Model Data Via Geyser (Custom Mappings Help?)

I'm working on a big project that uses Oraxen (a Items Adder Plugin) to make custom items across Bedrock and Java, everything is working fine except that i need to create multiple textures with different model data on one item, ex- Emerald Pickaxe and Amethyst Pickaxe that both use a Diamond pick as a base, i dont know if im using the wrong format or if this just simply isnt possible, but when i try this conf (see below) one just overrides the other and if i simply re-list the item then i get a Duplicate Key error and neither texture works. If anyone has any knowladge about this plz help and thanks in advance bcs this is a very specific topic and i cant find help for it anywhere online. | geyser_mappings.json | - "format_version": "1", "items": { "minecraft:diamond_pickaxe": [ { "name": "amethyst_pickaxe", "allow_offhand": true, "icon": "amethyst_pickaxe", "custom_model_data": 1002 }, { "name": "emerald_pickaxe", "allow_offhand": true, "icon": "emerald_pickaxe", "custom_model_data":1013 }
], "minecraft:diamond_axe": [ { "name": "amethyst_axe", "allow_offhand": true, "icon": "amethyst_axe", "custom_model_data": 1002 } ], "minecraft:diamond_sword": [ { "name": "amethyst_sword", "allow_offhand": true, "icon": "amethyst_sword", "custom_model_data": 1012 } ], "minecraft:diamond_shovel": [ { "name": "amethyst_shovel", "allow_offhand": true, "icon": "amethyst_shovel", "custom_model_data": 1000 } ], "minecraft:diamond_hoe": [ { "name": "amethyst_hoe", "allow_offhand": true, "icon": "amethyst_hoe", "custom_model_data": 1000 } ] } } My end goal is to make a amazingly fun and stable server with a plethora of custom items, armour, food, ect that work across the versions.
