What did Eastern Han Chinese sound like?

Question

As I was improving an answer to this question in the History SE, I discovered that the prestige Luoyang dialect of the Eastern Han and Three Kingdoms period didn't actually fall under Old Chinese but something called 'Eastern Han Chinese' which had already begun shifting consonants and vowels and dropping syllables' final consonants. As such, the Baxter-Sagart and Zhengzhang lists of reconstructed Old Chinese that you can easily find, eg, on Wiktionary don't actually describe what the language would have sounded like.

Does anyone here know a good source for trying to reconstruct what fairly accurate Three Kingdoms names and language would have sounded like? For instance, can any of y'all fill in the missing blanks here?

Modern: Cao Cao, Liu Bei, He (河), Jiang (江), Wu (吳)

Period: _______, _______, _______, _______, ________

Zheng.: Zlu Sau, Məru Brugs, Gal, Krong, Nga

Answer 1

The main go-to source is Schuessler's 2009 work Minimal Old Chinese and Later Han Chinese.

As this "Later Han Chinese" is of the 1st century CE, it falls directly in between the Zhou Dynasty's Classical Chinese and Qieyun 切韵 of the Sui dynasty. It is the pronunciation of the 说文解字, of the 释名, as well as early Buddhist literature with all their transcriptions of Pali and Sanskrit.

However, Schuessler states that:

The conservative strain of LHan, which is provided in this manual, could perhaps also be called Mid-Han; it can be converted to that of Eastern Han mainstream literature using the following paradigms:

... and then proceeds to list six points, five of which are vowel changes, one of which is velar palatisation.

The relevant points under its general phonology section are:

1. No consonant clusters
2. Velar palatisation (notably of 支)
3. Tones emerge definitively
4. Final -s is preserved from Old Chinese
5. "Vowel bending" - a definite great vowel shift for Chinese in this period, intermediate between Old Chinese reconstructions and the system in Middle Chinese.
