About smoke screen...I guess that replacing the bold effect with some smokescreen effect could be possible...now about sensors...the smoke will elude the visual sensors, no? I have no idea if this will work...but at first I guess that will not work...anyway a more deep "think" is need on this matter to evaluate if it is possible or not.
Probably Privateer, Anvart, DD, OLC also could have some idea on this issue.
