308 Win - Rechamber?

The kimber 84m action is designed specifically around the .308/30-06 case diameter that's where they get weight savings there isn't enough meat in the chamber walls to go WSM. Kimber has a larger diameter action for magnums. I think the biggest he can get away with is the .284 win but that may be pushing it. This is based on my understanding of Kimbers web site.
A while ago Ardent posted a pic of the regular Kimber beside the "new 84m" there isn't any metal to spare.

Because of current shoulder dimensions, might be hard to rechamber without setting it back and you might not be able to set it back enough if you don't have enough shank to work with. It's possible a 30-06 AI can be done as long as you have a long action.
