It can be done but why take the chance, especially with a McMillan. Take it to a good gunsmith and let him do the work. I debated the same thing myself when I switched from a two-piece TG to a Williams one-piece for a Win 70. I decided to send the stock off to Redneck to do it. He did a GREAT job with it. He is a M70 expert but I think he is willing to work M700s too. Send him a PM and he'll give you a quote.
