I considered chasing in some runs, just for neatness*, but how the hell do
you get 50mm from both sides of a 100mm wall? The cable would always be a
bit off-centre and it's more than 0mm thick.

That's easy. Chase 2" deep, fit cable. Go to other side, chase, adjust position to ensure it's the full 50mm deep Plaster, or should it perchance prove necessary, rebuild wall.
