[1.11] Custom item model with ItemOverrides

I thought it would be straight forward to create a custom model format with item overrides, but for now, I don't see how. What I tried so far was the following:

private static class ModelWrapper implements IRetexturableModel {
  //....
  private final ItemOverrideList itemOverrides;

  @Override
  public Collection<ResourceLocation> getDependencies() {
    return itemOverrides.getOverrides().stream().map(override -> override.getLocation()).collect(Collectors.toList());
  }
}
private static class BakedModelWrapper implements IBakedModel, IPerspectiveAwareModel {
  //....
  private final ItemOverrideList itemOverrides;

  @Override
  public ItemOverrideList getOverrides() {
  	return itemOverrides;
  }

}

apparently this is not enough. Currently, when one of the overrides is triggered, I'm presented with the MODEL_MISSING, instead of the item override I want. As an example, a model file would look like this (with easy to guess format):

{
    version: 1,
    mesh: "mhfc:models/item/model_b_hunters_proud_idle.mcmd",
    textures: {
        "#weapontex": "mhfc:weapons/(B)huntersproud"
    },
    overrides: [
        {
            "predicate": {
                "pulling": 1
            },
            "model": "mhfc:item/b_hunter_proud_0.mcmdl"
        },
        {
            "predicate": {
                "pulling": 1,
                "pull": 0.65
            },
            "model": "mhfc:item/b_hunter_proud_1.mcmdl"
        },
        {
            "predicate": {
                "pulling": 1,
                "pull": 0.9
            },
            "model": "mhfc:item/b_hunter_proud_2.mcmdl"
        }
    ]
}

all the referenced files do exist but still, nothing is being displayed
