I think changing things like this with SK is fine - after all, you are interested in the role-playing aspect of the game. Making a few changes would enhance your enjoyment - after all, if you were running a PnP game it would be acceptable for you to make changes to enhance role-playing if you see fit. I view this in the same light. Go ahead and have fun
