Ahh yeah, that's a good idea. But I kinda like what Raid suggested with it not being chargeable at all, and the amount of damage depends on how many times it's been volleyed back.
I do reckon the sword should be used as a side smash, though. I mean... when the heck did Ganny ever use his elbow? I think while you're holding the button and thereby charging the move, he'll have his hand on the sword handle protruding from his sheath, and as soon as you release it, he'll swipe it forward, like in TP. A sidwards slash kinda thing.
EDIT: Which will mean he wouldn't carry the sword in his idle. It'd be sheathed, but used for certain attacks, I reckon. *Just forgot to add that*
