Sorry Jester Boy, but Blue Coal is said to advance everything, so I assume that it would advance a machine gun to shoot bullets at insane speeds. I mean you are the Joker, don't you like a bit of insanity.

I can get into the airships and mechs thing cause steam powers those things but how does steam power enhance a machinegun to fire 100 rounds in 2 seconds? Remember that the Gatlinggun has been developed one year before the start of the scenario. 

EDIT: just a question, not trying to start an arguement.
