Somebody added the cast suggestion here.
Now we have 3 problems.
1) Eddie H. Wang.
2) about the "co-director" topic, if you remember well on the "Goddess of Mercy" Affair, the symbols 聯合導演 (Chor Yuen is credited in this way in the
Chinchanchung's HKFA book for that film) may mean "assistant director". Maybe it's better credit them as "executive director" ? For the moment, Chor and Dao will be "executives".
3) You suggest the "production managers" (製片) as producers, but they are not. In the entry of your film (2711), there is a producer (監製) and a production manager (製片). Maybe your translation is not correct. You have remembered me a sad episode with Mr. Chinchanchung...
Added the rest of them.
