What often matters is the interface between the dust shield on the FH body and the seals and/or shield on the axle cone. If they seem to jive OK, then I'd give it a whirl. Removing the old dust shield and installing it on the new FH body could work but you have to be careful not to damage them, as they're easy to deform.

In the bigger picture, that hub's relatively affordable and you could get a brand-new one for the parts. Then you'd have a new FH body and cones, so there'd be no fussing with seal/dustshield compatibility as they're a match. In fact, here: $12. http://www.cambriabike.com/shopexd.asp?id=84599
