Bumping an older thread here, but Wow... this guy was definitely headed down the same path as me!  
 
I gave serious consideration to a set neck on my custom, but opted in favor of 3 purpleheart lams instead. Love the classic soft-horn Omega, and the simple circuits. I probably would've gone with the Crown headstock on a 4-string, but hey - that's why they do custom builds.  
 
Nice!
