I don't think so. What the GDC said was that under <R76-B>, any rod-locked cylinders used for storage must be downstream from the primary regulator. <R76-B> calls out what components are allowed to be in the high-pressure side, and states that those are the only ones. I don't see any cylinders in there.

<R76-A> states that cylinders must be downstream of the regulators.

So, under <R76> in general, if you do manage to figure out how to use a cylinder as a storage tank, it has to be downstream of the primary regulator.
