Won't work I'm afraid.
However you can convert the saves and the conversion process should be very simple.
Me and a friend share save data for a few of the games we play which is fine for most games, but I happen to have an NTSC copy of Brawl whereas he has PAL.
So I was forced to find a way to convert the saves back and forth. I found a program that someone made to convert NTSC Brawl saves to PAL but I had to find out how to convert from PAL back to NTSC manually. I found that all I had to do was edit a couple of things in the save in a hex editor, and brawl is a game with a larger save file so I can only imagine it being easier for other games. I'm sure the process does vary from game to game but I can tell you how I convert Brawl saves if you want.
