Really quick, I was thinking about this last night, our radar should stay active while we hack or pick locks and we should be able to get attacked while this happens. Also, my buddy Ivan Ratner said that the risk of being ghoulified would be a good addition. You only have a certain amount of time to cure yourself before your change becomes irreversible . Like after a certain radiation level you have that warning pop up on your screen that your are showing signs of becoming a ghoul and you have to rush to a doctor, or some cool new drug, to cure yourself. Maybe add some points to your endurance and subtract some from strength.
