I don't think that there is any way. As in, the militery brass you have two small flash holes in the case. If you were to drill a regular flash hole in the military case it would be oversized, as there would now be three flash holes in the primer pocket. This would lead to having a flash back of hot gases blowing out the primer and sending hot gases back into your face. I do believe that I read this in a reloading manual. The flash hole has to be a certain size only.
Now if you could silver solder the primer pocket in, and if you had the right sized drill bits you might be able to do it, but I wouldn't recommend it as the pimer pockets are a vital part of the case, must be the right size and depth and the correct size flash hole!
