I have strong doubts that this feature will be usable, but
assuming that it would be...

A much cheaper way to implement this is to just change what
is being written. Then you don't need to lighten the mask.
The first blob is 0x00 (not #000000, because greyscale), the
second is 0x01, and so on. It wraps around of course.

I have often thought a save-as-stamp option might work OK.
Choose the predominant edge color as see-through, then trim
away the excess and let the result show up as a stamp.
