Send a thick donor core to a good Luthier and he can hand carve it for you, will cost way less than $14k, and if you want all hog then that will be at least one Santana fixed
I've had MANY thoughts in that direction. If there were a way to know for sure whether the neck from a Silver Sky (USA or SE) or a PRS CE model would fit into the neck pocket of a Warmoth V body guitar, that would be the path of least resistance. If only there were a PRS online guitar forum where I could go to ask people whether that would work or not, that would be great!
