Difficulty in replacing a FT lighting wire (no CPC)

I am encountering difficulty in replacing one FT lighting wire,
no CPC. It has been run in concrete, with hessian embedded,
on crap-block-coke wall, with chicken wire overlay & plaster.
Removal may damage flock lined wallpaper on the other side.
It is the sole 2-core cable drop to a switch, although I notice
another switch & light the other side which begs the question
of how that receives a supply or return with no other cable.
The alternative is 4mm^2 6491X to the architrave backbox,
right back to the CU (or a locally FTE rewired lighting circuit).
No class-1 lighting device, metal backbox needs an earth.
Is this still regarded as good practice?
Wouldnt it be easier to replace the pattress/screws/switch?
