According to the jpegtran authors, "wipe" is intended as an option to discard (gray out) data inside a given image region while losslessly preserving what is outside.

I'd like to suggest adding such feature to the JPG_TRANSFORM plugin.
As alternative i've tried jpegcrop but it seems to produce broken images.
