fluid 360 head and body turns on y-axis

Hi

I am still learning, so I apologise in advance if this is already possible.
Is there a way to create more fluid head and body turns, a bit like what can be achieved using https://aescripts.com/joysticks-n-sliders/?
Currently the solution seems to be to make more layers in Photoshop/Illustrator in-between similar to

Is it also possible to do a full 360 rotation of body on Y-axis? I assume there will also need to be rigging layer flips/re-ordering to achieve this?

Thanks
