Yep, the first thing I tried when I had to deal with this was using InputEventSensor, but� I couldn't manage to use it for changing the mouse position.
As the InputEventSensor takes the position from the hardware cursor as you say, the workaround we found was actually changing the hardware cursor's position using FFI :P

But it looks like we do read that from primitives. Not sure there is a
way to do that.
Interesting question!
