I don't think so, as far as we know there is no sacred dragon-slaying sword with the same strength as Gram, for example if Ascalon were used, it would probably do the same damage as Gram because despite the advantage, Ascalon is weaker than Gram. So I believe that adding the advantage, it would do the same damage as Gram, but if a sword as strong as Gram was used, it would probably do twice or even triple the normal damage
