I don't think I am understanding the issue correctly. Your CCW's are almost touching the calipers, correct? You do not want more spacing between the wheel and hub face than there already is, right? Thus the resolution is a deeper offset hat (which I believe is the new kit, where as the old one had less of an offset) and accompanying mounting bracket. Correct?
Or is the difference in offset between the old and new JSK hats actually come from a thicker aluminum hat. I don't think that would make much sense, but it is possible. I would think that JSK could just make you a hat with more offset and an accompanying bracket. Albeit at more cost.
Ignoring the E-Brake caliper and such, the drawing below is a true representation of the JSK kit I have. The green highlighted face is the face to simply move farther in board and then obviously the hat would have to be offset more, but the thickness of the actual mounting surface would not need to be changed...
