That is, multiple smaller cylinders, EACH FILLED THROUGH A SEPARATE SOLENOID VALVE, will fill faster than one big one filled through (as required by the rules) one solenoid valve.
Maybe I'm misinterpreting the rule and the conclusions you're drawing from it, but no inspector has ever faulted us for having one solenoid for two pistons.

Why would filling two pistons from one solenoid, vs 2 pistons from 2 solenoids, be faster?
