The title says it all: what if Vader used a double-bladed saber instead of a single blade? What modifications would he make to his suit and lightsaber style to accomodate the double blade that Maul and the inquisitors made so iconic?

I feel that the top of Vader's suit would stay the same, but that his legs would be more like Maul's spider legs. He would need to be able to manoeuvre more quickly with a double blade. I feel he would also benefit from having a ball joint or something along those lines so that he can actually bend and turn more easily, rather than be the stiff Vader we all know. Not so sure how easily that would be to make though considering he still has parts of his legs, whereas Maul didn't have any part of his lower half left.

What are your thoughts?
