Have a read of this thread by Chris Jones. Human Progress
Plugging into radius definitely works (I’m using it) but you might have to modify your map (I use a Hue/Saturation node to reduce the intensity to tiny tiny levels). Chris put screengrabs of his node tree in the thread. I’m personally finding that mixing individual shader nodes (SSS, diffuse, glossy) rather than plugging everything into a single Principled Shader node works best and is more flexible.
