Ridley Scott's "Prometheus": Idea for a skin

Some minutes ago, i had an idea: a skin based on an Engineer, as seen in Riddley Scott's movie, "Prometheus" (2012). But on which champion?

My first thought is Brand ! Instead of fire, he throws the Black Goo! (you know what i am talking about if you have seen the movie) What do you think? Is Brand suitable? Do you think that another champion would be better in that?
