I agree with the conclusion that, as written, the rules appear to allow only the single tank from the KOP to be used or an additional tank if acquired through FIRST Choice.

Given the availability through FIRST Choice, my belief is that the rules will be amended as necessary to allow additional air storage tanks. The limit of a single solenoid valve per movement (<R74>) limits the power level of any individual cylinder motion so limiting the max storage volume was likely seen as unnecessary.
