That seems like it could be pretty interesting.
I wonder how it will stack up with RoC and Liber Chaotica?
Well, with RoC, the 40k elements were an afterthought added by Bryan Ansell, and with the Liber Chaotica, the material is presented from the perspective of an increasingly-insane scholar in the Warhammer World... so neither, I feel, are directly comparable (though they're both obviously part of the vast mass of inspirational material).
Personally, I think it stacks up pretty well, but that might just be because I was involved in writing it.
