To my knowledge no. There are too many things that can go wrong. Text is one of the big things that leaps out at me.
With that being said, try using your (J).sav with a (U).nds and see what happens. I think some of the Zelda and Pokemon games share the same data structure so they are interchangable. In fact, Pokemon Diamond saves can be used with Pokemon Pearl games so you can really "Catch'em all!"
