That still won't help. While HKEX breaks from 12-1, many other Asian markets are active during that time, such as Japan, Korea, SGX... to name a few. And the US futures market are also active during that time. Can you do weekly reset instead of daily?
not that simple as it is a time to refresh databases, update contracts, symbols etc. the resets have gotten briefer and longer term projects are in place to reduce or eliminate them but this won't change overnight.
