Absolutely. I see no reason to special-case dual wielding, if you're strong enough to swing an item that big with each hand, let the claymores fly. If you aren't, well, that's what magic's for.
Considering the wrist has very few muscles, it'd not be something you could train for, you'd physically need to be able to support it, mainly with your bones which for an unbalanced sword almost as long as you... ain't gunna happen. Also if you could use magic to over come it, why not use magic to swing it around like a phantom sword...?
