In fact i didn't continue that research, i tested some shaders from SP maps, and i am regrouping "cool" shaders into one map(like bloom/transparent,glowing shaders), as reference shaders and some customized shaders too, and of course once i get what i want i'll release the patch for that map with the shaders.
I am creating bloc box's for each shader tag, so that way i am able to test multiple shaders at the same time:
Here 3 box's from left to right : bloom shader, distorsion shader(+ 3rd person "reflection") and a metal shader
