Sure, it'd work fine. Midway even has the reamers, PN #280-149. What you'd end up with would have the performance of a .308, wouldn't feed for beans through anythong but an action designed specifically for a WSSM case, and you'd either have to make reloading dies or pay somebody a lot of money for them. It probably would make a decent cast bullet benchrest gun, but so does a 30 BR. And there is the lack of quality brass available for it. But yeah, it could be done.
