Since the whole point of sizing is to reduce the brass to some size smaller than the chamber it won't work. I have heard of people cutting sizing dies using chamber reamers though.
I see no reason why it could not be done. I believe the die will have to be annealed for cutting then rehardened afterward. As belaw points out, such a die will not reduce the case to a smaller size than the chamber, so using it to size down cases fired in a different rifle might not make them small enough to enter your chamber. But they certainly woin't excessively work cases that you fired initially in your rifle, so if those cases will go back in your gun and allow you to close the bolt, your die won't mess them up.
If you have your rifle chamber polished up a little more than the chamber in the die, it might just work slick as hell!

BUT, you still have to do something about sizeing the neck of the case to hold a bullet! And a neck sizeing die is available "now", and cheap compared to makeing a die that will need neck work anyway...
I saw BR guys trying things like this in the 70's and all ended up just buying a quality neck sizeing die in the end...

do a search here From what i have read, i would say NO, you can't make a FL sizing die using your chamber reamer. I know for sure, that if you neck size only, soon or later after 3 or 4 firings, the rounds will no longer chamber in most bolt rifles. If the Fl die is made short, so that the shoulder is bumped back a few thousands, maybe then, not sure. I would send 3 fired cases to Redding and have them custom fit a FL type S bushing die for your rifles.
