Hypothetically I wonder if it would be possible for Lemmy to federate some kind of hashed version of your private blocklist, such that no one could decode the accounts it references, but at post-time a username could be checked against the list and blocked from replying?

That’s not quite sufficient. Look at a bit more advanced cryptographic stuff like Snarkblock.
You still got the issue that blocks WILL have a publicly visible effect when you block somebody who already have replied to you.
