Exactly... Jason laid that out pretty clearly in his post. I recognize parts, it's really ingenious parts useage to make the ultimate Jedi LUke (I'd have used softgoods for the skirt I think), and a nice figure.
Don't we all wish Hasbro was this creative?
Hell, they practically own all those parts ready made... It'd only require a little torso modification on their part, but minimal mold tooling overall... Simple swapping around, and voila, perfection.
