Plus, this isn't even that big of a deal.
I've used tons of stuff that Shenske and LJ42 posted in White or Orange/Black style, and I've always changed the spines to look like the Japanese covers. It's just a matter of cutting the top part of the spine from the template you want and pasting it on top of the cover you want - no big deal. Should be more than possible even in MS Paint, and definitely in Gimp, for those that can't afford Photoshop.
