Deferred shader Translucency

Unity Engine

How Can I edit Deferred Shader to enable Translucency?

The two way that I’m thinking about:

  1. Modifying the Internal-DeferredShading shader. Actually would be best. But I’m not sure Can it operate with the variables/properties?

  2. Local shader solution. Calculation inside a regular shader then add to GBuffer3? Some other effects usually working like this (for example Ambient Translucency part works). But I see the problem is in the light attenuation? Can it be workarounded inside the shader?
