Dewarping it mathematically should be fairly easy if the lens' gravitational field is sufficiently uniform. Problem is more the amount of detail we actually have in these pictures to expand the most compressed parts.
I wonder if correctly dewarping would help get a measurement of distance of the lensing object. Would that then be able to help recalibrate/confirm our understood distances/scale/etc?
