The fae you were thinking of was the nursery boggle Rawhead and Bloody Bones, there are copius amounts of data on him available on teh interwebz.

But yeah, the more I look into LKH's Noble Fae, the more I think that with a few additions and a little alteration, they are, essentially, the same thing as the Primals represented in the Armageddon series, right down to aspects and power focus.
The Hands of Powers will have to be dealt with a little more delicately, and the Lesser Fey would probably need to be handled collectively, but all in all, the fit is pretty good.
It's the Sluagh where I would have the most fun.
