David,
I know you have already considered this, and I can appreciate wanting to build something for yourself, but how far is the 700 CDL-SF from where you want to be? It has a 24 inch barrel and 700 action with a laminated stock. I would say that it could be had for about the same money you are talking about spending to build.
In the end, brother, it is your dime. Get what you want.
