Wow,
Some impressive image editing skills here... I really feel humble with my pathetic attempt, I think it would have been easier to carve a model out of wood and take a picture, but here goes. I think a BK5/BK15 blade scaled to a BK14 grip, thinned a little with a little more blade sweep and a little up angle from the grip and no swege. I think the extra sweep and up angle would help compensate for the size reduction, and still leave this as a very usable all purpose field and slicer blade.
Not sure if the picture will show, but here goes...
