Actually, you would not have been able to load the D2:ED saves in DKS, anyway (there were too many changes made to maintain saved game compatibility). They would have been compatible with the add-on installed, and when you were done with that character you could have installed a D2:ED+FoV to DKS conversion patch, if you wanted to play the remasted D2:ED with a different build.
With DKS, you can either start in Farglow again, or create a level 35 character at the beginning of the FoV section of the game.
