I am now thinking maybe:

1.) Lay it out carefully with pen/marker (might be 9 sq. feet).
2.) Hammer drill with 1/4 or 5/16 " percussion bit every inch or less.
3.) Hammer and cold-chisel to detach "plaster".
4.) Recip saw to go thru steel mesh.

Is viable? I hate to knock huge jagged edges in the "plaster"
which does not break predictably with hammer/chisel.

Could be -- but it's still going to make a hell of a mess. I still say
use a hammer and chisel to remove the plaster. If you're having problems
with the plaster not breaking predictably, I'd say that's probably due
to your technique. Don't try to chisel all the way through it in a
single blow. Instead, score it lightly all the way around, just deep
enough to get through the whitecoat. Then score it again, harder, about
half-way through the browncoat. Finally, chisel all the way through the
browncoat.
