I linked to the paper because it wasn't clear if OP's goal was to increase the security with the cascaded hashes or not, and also because I personally found this result very surprising and interesting when I first learned about it.
If you have a moment can you please elaborate a little more on your second paragraph? Are you describing applying a similar method inside the compression function of the hash function? Any hash function? Where does the parallelism come in? Thank you!
