Better motion blur? (with HDR pixel weights)

The default motion blur in the PPstack, legacy image effects or any other 3rd party motion blur on github uses the same pixel weights to blur the samples, which cause an inaccurate look. Normally overexposed areas in photos like direct light sources stay lit in all samples like the photo below. Is there a way to use the HDR float values to overexpose the intensely lit pixels across the samples to give motionblur a more realistic feel?
