There is lots of good info in the luthiers section. It might be worth starting a thread.I like this kind of project. Not equipped to tackle such, but it's a cool, worthy problem to solve.
Many years ago I repaired a Les Paul with a badly broken headstock by making a new headstock and gluing it on with a scarf joint under the fingerboard.
With the 1/2 size upright, I’m thinking of doing something similar if I can find an unfinished neck.
