It might work, in the comics, Iron Man is Tony's Starks cheif of security,
something that probably won't work very well nowdays. (Nobody is going to
trust a "Chief of Security" who always wears an armoured suit and nobody
nows his name).
Also, since it is the thing now for young millionares to be socially active,
if the head of Stark Industries wants to play superhero, let him.
