If things don't work out with Mr Warmoth, necks can be fixed.

I'm always fearful when installing these bushings, yes, they are supposed to fit but I don't like them, that's why I switched to the planet waves and now the hipshots. They use a reach nut. If you don't do it yourself, probably take a luthier half an hour to fix, probably cost you $25. It'll be good as new. Might as well have him install the tuners if you're going to stick with these vintage guys, another $25. Should be less than $100.
Depending on the glue, the neck will be stronger than before.
I'm sorry.
