The shop guy said the neck was pretty much a write off. In his opinion, there ain't a whole lotta meat left on the worn ones.
I know the neck is functional. I used it for several years ont he jambolin. I had intended to put the kramer neck back in the right place so I could quickly get a floyd guitar up and running. I did and now it looks like the floyd is worth installing on another guitar.
As far as levelling goes, one of the biggest contributor to the difference in wear is that my clown guitar that I used the neck on for so many years joins the body at something very conservative like the 15th fret. I can't even really reach those higher frets because there is no cutaway.
I am thinking that I can rather forgivingly take some height off the frets that I can't reach anyway so that I can get the 7th fret on the G string to work again at least.
The neck feels nice to me, but evidently I am a terrible judge of guitar harware. This guy told me that it had a twist. Since it's arguably garbage, there is not really anything to loose from going at it with sandpaper, scotchbrite, files or dremel, especially if I can contain the damage to those higher frets.
