(If you ask me -) not local luma of 1st clip, not average luma of 2nd clip. Local luma of 2nd clip.
Idea is: don't use just one radius for blurring all pixels in a frame, but:
blur each pixel using the radius that is given by luma value of the corresponding pixel in the 2nd clip. I.e. the filter would have two arguments like "min.radius" & "max.radius", and for filtering the 1st clip it would use min.radius where 2nd clip is zero, max.radius where 2nd clip is 255, and inbetween radii for 0<2ndClip<255.

The idea is good (it ever was :D), but I could imagine some problems regarding implementation, or regarding the speed of that filter's performance ... :oh-oh:
