I may consider coving if the result turns out badly but its not a square
shaped room and requires 12 off angles none of which will be truly 90
degrees.

I fairly recently fitted an artificial cornice to my Victorian living
room. The original had gone due to war damage - long before I bought this
house. I got the closest match I could to next doors - theirs is still
original.

I do have a decent sliding compound mitre saw.

The artificial stuff is quite flexible unlike plaster. And my ceiling were
anything but perfectly square.

Still very pleased with the results - but it's not cheap. And don't skimp
on the adhesive or use a cheap one.
