A public Merkle tree like the certificate transparency logs can serve the same purpose a million times more efficiently than a PoW blockchain.

True. But its not programmable, in the way that Ethereum is for example. And that would be a nice feature to have in a payments system. PoW would never make sense for the Fed anyway - more likely PoS with some combination of Member Feds and participating FIs doing the staking and validating would make more sense.
