Is there any way that they can be stripped back to the original wood
surface in situ without wrecking the surrounding ceiling?

Not sand.

And, if possible mask up the ceiling with something fairly tough.


They can blast down to about 2-3inches resolution, maybe better if they
take the time., so that's how far the damage will extend, and it tends
to be mild pitting not total destruction. Even if the masking gets
ripped, its better than nothing.
