A MOSC rom11 will never have any problems with the keyroll because if it did the genuine punters cards would also have a problem. I dont think even VM would write code that did work on their own cards would they!! The only problem ROM11 cards have are attacks from VM if they identify the image on the card as non genuine, if your image is as close as possible to a genuine card image, ie tier list cam ID rights dates etc, and is not in the public domain then it would be very difficult to single it out for attack.
