I assume the tubing diagram would look like this:

Compressor --> Upstream Accumulator (115 psi) --> Regulator --> Valve --> Downstream Accumulator (60 psi) --> Cylinder
T-junction connecting both the downstream accumulator and cylinder to the valve......
Absolutely correct!

One note:
To maximize the air flow from the downstream accumulators to the cylinders, use double ended accumulators and feed into one end, putting the "T" between the valves and accumulators, then run the hose from a straight fitting on the other end of the accumulator into the cylinder, also with a straight fitting. Avoid using the 90deg fittings if possible.
