Well for starters its not entirely clear whether the "Shturm" optionally manned tank is the most efficient answer to the problem from the Russian POV. The project predates the war in Ukraine by many years. I suspect it was envisioned as a way to give some use to the then huge reserves of stored T-72, against the background of the vast adoption of the Armata platform. Nowadays the Armata program is delayed and won´t be aquired in large numbers at least after the end of the war and the T-72 stocks on the other hand have diminished significantly.
Now, from the Chinese POV the situation is very different. I guess the most efficient solution would be to take this new 40 ton tank and change its turret and armament for what is needed at the moment, and also developing several kits of add on armor with different weights and protection capabilities. I suspect much of this (especially add on armor kits) has already been done. But for example, if they deem the 105mm insufficient for urban combat, just develop a turret with a shortened 125mm with higher elevation angles and modified bustle autoloader to fit these rounds, to be installed specifically for assault missions on urban aglomerations.
