I can't imagine setting the intonation on that thing, or how you can have it "close enough" up and down the fretboard with a magnetic fretboard.
But, I also imagine "How are we going to keep the intonation with a magnetic fretboard even remotely accurate?" would have to be the first question anwsered when designing such a system. So, who knows?
Could be cool if you lived in such a way that you could only have one bass. Nomadic Motorcyclist springs to mind, but I don't know if there is enough money in it to afford a $1000 aftermarket neck.
Hmmm.....
