I have tried this XL400 BOAR'S HEAD with 2 PPCs and had great success with it. Again - crazy/suicidal, but strangely effective with the speed advantage.
Getting back to the OP's build... someone mentioned keeping the LLs in the left arm to avoid losing them when RT is blown (STD engine builds), and I liked that idea, so here's a variation on the OP's Behemoth with that tweak in mind: BOAR'S HEAD
Edit: Thought I was posting on a different Boar's Head thread. Disregard any reference to the "OP"
