For comparison:

A sha512 hash in hex: 309ecc489c12d6eb4cc40f50c902f2b4d0ed77ee511a7c7a9bcd3ca86d4cd86f989dd35bc5ff499670da34255b45b0cfd830e81f605dcf7dc5542e93ae9cd76f

The encoding also seems to be HN-safe, using no emojis or other things HN filters. The font used here is lacking some of the characters, but that shouldn't matter if you just copy-paste.

That base2048 string is 114 bytes (vs 129 for hex), so it's only significantly "shorter" in what you see, which isn't exactly human-readable (actually, less than the hex string; for a quick visual inspection comparing just the first and last 2 or 3 characters is enough, but that's a lot harder to do with all those unfamiliar Cyrillic, Tibetan, Tamil, Armenian, Arabic, Samaritan, Greek, etc. characters in there).

  Original:  64 bytes, 128 bytes in hex.

I'd prefer base58. Maybe compress it first.
