Heavy utility obviously, the heavier the better, but heavy attack is a question.
From a supply perspective, like
@luciferdd has said the primary component aka 1600~1800kW WZ-10 turboshaft is ready now, would be easy to build a heavily-armored version of Z-10 or even faster to license-build a Russian Ka-52 design with Chinese components.
But the real question is whether PLA wants it? I think drones and loitering munition may replace "flying tank" type of heavily armored helo, while "flying cavalry" type of manned helo are still useful in missions like ambush/recon, hunting HVT, escorting an air assault formation, etc especially in complicated terrains. With continuous improvement of powerplant (WZ-9C/AES100 turboshaft) and avionics, I think Z-10 can well serve PLA needs in the coming decade, focus will be building drones.
