How to apply DOF blur after postprocess material?

Hi

Im trying to achieve a predator’s like thermal vision post process effect, to this moment I can make the effect work but not in meshes with a translucent shader. Here you can see the screenshot from the vieport and the material network.

The blur effect is achieve with this settings of DOF

To get the all the image blured I set the material to be Before Transparency (this is the only way a find to get the DOF after the postproces material) but this make the translucent shaders to be excluded from the posprocess.

Is there a better way to achive a blurred effect in all the screen?
