I've done stealth wizard.
I teleported into mime office, became mime, got an ID from HoP, danced and was silly in front of bridge, whereupon the captain let me in. I ei'nathed him, yes, and misted away. During scry orb, ghosts tell me captain brain is being transplanted, but crew still doesnt know what happened, and thats where I finally figured out what I'm doing. I make my way into medical, steal the brain just before CMO is placing it into the new body, then as CMO chases me into the middle of medical, I ei'nath them too, somehow with no witnesses again, and take the brain. I then get the head of security in the halls, and the HoP in command, just as crew figures it out. My plan was to only kill command, then inform the crew they are free of their shackles, but the CE and a wily sec officer with a shotgun (old shotgun with slugs etc) got me before my plan could be realized.
