YES!  I have wondered why Nikon don't do the same thing within the range of 
their scanner Depth of Field. It would nearly double warping that could be 
tolerated before losing focus. The only downside is that you would have to 
put the film/slide in the "right way round" regarding film curve, not 
regarding mirror image sense.  This would not be a problem if documented 
clearly.
