Coming from the out there left field, I'd considered making a body of rick shape by cutting out lamination layers, each layer with the appropriate detail cut thru it first, ie neck pocket shape and routs, and then gluing the lot together to make a "ply".. this meaning you can construct it without a router or anything fancy tooling wise. Hopefully you see what I mean.
Accepted you may not in fact want to do any woodworky stuff yourself, but just a thought.
