Any 455 to ACP/AR conversion would still allow the use of 455 Mark II since they are slightly longer than 455 Colt. And since the case mouth would headspace on the original chamber shoulder, once faced off, the case head would extend out of the chamber slightly and have the same relationship to the firing pin for reliable ignition.

If I were to convert one to ACP/AR I'd leave a slight rim on the circumference of the cylinder face to eliminate the need for a new cylinder stop in the lower corner of the cylinder window. Or better yet recess the chambers for the AR like for the 45Colt to retain the original cylinder serial number. I could still shoot ACP individually w/o moon clips since I hate them anyway.
