Blended Edges on Tree Creator Leaves

I need help with making Tree Creator trees to not look so pixelated. The default TreeCreator shaders appear to have hard edges because they just clip/cull if below a certain alpha.

I can get the look i want with various other shaders such as 'Mobile>Particles>VertexLit Blended' or the Alpha+Cutoff technique found here >> ShaderLab syntax: Alpha testing

But... those are static and won't animate with a WindZone because they don't include the vertex transforms like in TreeCreatorLeavesOptimized shader.

Update: Made some real progress on this problem and its mostly working; what sort of improvements can be made here? can it be done without the second pass? Also, is there a way i can reference the native Tree.cginc so i don't have to copy it into the project
