Milling Redhawk Cylinder

Thinking I might want to get the cylinder milled on my 454 redhawk so it can take moonclips and thus fire 45 acp. I have a bunch of 45 acp ammo laying around from when i used to have my springfield, so it just makes sense for plinking. I was wondering if anyone has had experience with this? Would it effect my ability to fire full house 454s in any way? Also a rough estimate on cost? Have done some research but couldnt find much info on it. If im correct, after I get this done the gun would be able to fire:

454 casull
45 colt
45 acp
45 super
460 rowland
45 auto rimmed
45 schofield
