One thing is for sure, whatever happens we aren't gonna be getting a job that's just about the gun.
One of the reasons they made MCH the way they did is because they said MCH just standing there shooting for all it's attacks looked really stiff and unengaging (iirc). They added all that extra stuff to give it more flair and give them more to work when when it comes to animating MCH's many attacks. That's also one of the reasons that a lot of their attacks make them look more like a gun mage than a regular gunner.
