I think that part of the performance gain of BLAKE3 is due to the fact that it uses a Merkle tree or something. SHA-3 has ParallelHash. One could use that with KangarooTwelve potentially. I would really like an AES-based hash function as AES-NI is much faster compared to chacha20. There was a function called echo that worked like that during the SHA-3 competition but it was dropped before the final round.
