Comment(by warner):

 That sounds good. Although, after reading quickly through the paper, I'm
 still not sure why we need the expander, if SHA-2-512d will give us 512
 bits of quality entropy, and we don't have any curves larger than 512
 bits. Does it take more than K bits to construct a private key for a K-bit
 curve?

 But, their arguments seem sound, and going with a respected standard wins
 in my book.
 Your proposal sounds fine to me.
