Modify normal angle

Hi guys! 

I have a grid, did a soft transform to have one side flat pointing the Y axis and another pointing the Z axis, as it is in the screenshots.

With a attrib vop I'm able mix the normals of a flat grid with the mod one (Red node)

BUT I want something like the last image, the polys that are facing Y has 0 deformation and the polys that are facing Z has 1 in the deformation, right now is 0 or 1, I haven't been able to achieve a soft blend between the two of them.

If I could convert the normal to angle, do some kind of "if statement" maybe this will work, but I have no idea on how to do it.

Any help please?
