You'd definitely have to mod it to be able to get this to work at least in terms of appearance.
Windshear isn't quite right in size or appearance, but it's ability might sorta translate to the Wind Scar technique. Unless there are curved Greatswords, I don't think you'll find an unmodded one you can use.
For Sesshormaru, you could mod the werewolf to be white to simulate his unleashed state. An Imperial sword or steel sword might work for Tokijin, and for Bakusaiga you'd have to go with a Blades Sword.
