Yeah. I think that it would be possible, but quite unlikely. I do believe that if a clone, commando or up most likely, felt love for a jedi that was in his scope during Order 66, he may not fire. He may try to protect that jedi even, but once the others realized this, I think that the other clones might kill this clone. (Probably not his own squad mates though) Its confusing me trying to type it, lol.
