I don't profess to know much about these things, but it seems to me that having a vacuum take off from only one bank of carbs/cylinders would only provide the necessary vacuum for 50% of the time! Therefore, I would expect that a vacuum take off is required on each manifold.

Yes, quite true, and all three ports joined too. It should be the total vacuum of the engine.

Got some reading to do

Hi clee
I think I have posted a reply to this question somewhere else on the forum.

Just a thought. Some Renault 30 V6's were fitted with a single, double choke Weber. If you could find the manifold from one of those, possibly it could be modified for a Holly or whatever. As I said, just a thought.
