I grew up in a 1917 vintage house with plaster over wood lath. Have lots 
of experience patching plaster cracks, and I've spread a little drywall 
mud over the years. It's been years ago (1980s) but I think it's still 
relevant to current materials: plaster cures (crystallizes) and expands, 
like cement; mud dries and shrinks. Mud is NOT good in large layers or 

We had a kitchen ceiling cave in from a water leak above. Dad's initial 
thought was rip it all out and drywall the ceiling. But we were still 
able to find a guy that was an expert plasterer. He laid a couple coats 
on it, didn't have to do much if any sanding, and it was ready to prime 
& paint. I don't remember exact details (been 25 or so years ago) buy I 
think he used something like tile backer-board or metal lath to replace 
the water damaged stuff, and laid a skim coat over the whole thing.

If you can still find a plasterer, I'd try them. Heard there's been some 
resurgence in the trade. Some high end houses go for a full skim coat of 
plaster over drywall, instead of just mud joints that dang near always show.
