None of these objections would apply if it were reforged. Even if the sword shown in WoR was longer (I don't really see how one can make a reasonable measurement of that) it would hardly be impossible that reforging it as a double-edged blade might make it shorter. Unless the hilt is important, there is no reason to believe it couldn't simply have been replaced or modified.
