Bad idea, only supposed to get you out of trouble with scanners that have
to do mask removal wholly in s/w.

Most proper filmscanners increase green + blue channel exposure to cancel
the mask without discarding a whole chunk of dynamic range, as happens with
s/w removal. If you scan colour negs as positives, this GB exposure
compensation doesn't happen.
