Being someone who has held THE Snake Eyes Sword while in the prop house that manufactured it, let me put it out there that these accelerator suits were merely foam molds. The final armor seen in the film is a digital composite over the cheap foam suits the actors were forced to wear as reference. They were a one-piece suit with, in actuality, almost no maneuverability; and they were extremely hot. My suggestion would be to gather as many ref-pics as you can and try forming it in sections so you don't have the same problems the actors did. Foam can be a cheap way to go about building this, and you don't have to wait for someone else to get their work done so that you can start working.
