I encountered this late last year when I was putting together our flailer system. I was waiting till this year to prove it, but here are my theories on what you need to do? If i understand correctly you want some pieces of your arm to move in the new assembly. I'm pretty sure there is no way to move the arm assembly as you have it. Each part that will move in any way will need to be assembled in the final assembly. Then you can use your motion constraints etc... If anybody else has more input on this I'd love to hear it.
