I have a similar house, with similar problems. (1907 Edwardian in the SF Bay Area.)
Leaks in the bathroom plumbing 70yrs ago led to delamination, and bad patching made it worse. Already fixed up minors problems in one bedroom wall, but still have to deal with something just as bad as yours in the hallway.
I'll be following this thread with interest. Thanks for posting!

If you go this route, don't use pre-mix plaster.
It'll shrink like crazy! :)
Go for the 30-90 minute powder you have to mix. Watch some YouTube videos. :)
Edit: Powder you have to mix yourself. Pre-mixed dries out and shrinks. Freshly mixed 'mud' will cure and retain it's shape. It's also a lot more durable when cured. (But. you're still gonna need more than that to cover this depth. :)
