Use reference photo to improve sharpening

It would be great if Topaz could allow us to give Sharpen AI a reference photo that would help it do a better job in sharpening. For example, I may have 2 very similar photos. My favorite one though is somewhat out of focus and/or has motion blur, but the other less interesting photo is sharp. Maybe a person who moves at just the wrong moment in the more interesting photo. It would be cool for Topaz to look at both the interesting unsharp photo and the uninteresting sharp photo in order to sharpen the unsharp photo.

I’m voting this up as a proposal.
