Something with such control features and endurance won't be cheap. It won't survive engaging any air defense asset either.
Trying to deplete SAMs by cheap Shahed like UAVs is a bad idea. The Iron Dome has proven by example that SAMs could be very cheap.
Its Tamir missile is already cheap enough to use against the simplest Iranian built Shaheds. And it is still a massive massive overkill against them. We are talking about an active radar guided missile that can shoot down 155 mm shells here. An artillery shell is a Mach 2+, small, very time critical and a very tough target. Toughness is important to mention because it mandates accuracy which means expensive subsystems.
Iron Dome and Tamir is about $50K each
Compare that to a Shaheed which is $10K to $20K
Again, if you have enough low-cost Shaheeds, trying to counter with expensive Iron Dome and Tamir is a losing proposition.
China can produce many more Shaheed than the defenders can produce defensive Iron Dome and Tamir SAMs.
Plus the side on the offensive can choose to concentrate enough offensive missiles at a single target, so as to overwhelm the number of defending missiles.
For example, a really heavily defended location might have 200? SAMs.
So you put together a strike with 300 Shaheed with a simultaneous time-on-target.
The defenders run out of SAMs and have revealed themselves to surveillance drones.
