While I am a (former) Flight Engineer and not an aerospace engineer, I can't see the design of "Roc" being feasible. I have no doubt that people more knowledgeable than myself (and those who think they are) will comment on this, but I would think there will be an extreme amount of stress on the "wing" between the two fuselages. And the Roc will fly like, well… a rock!
