Pneumatic Proportional Control Valve

Our team is prototyping a pneumatically driven catapult shooter. We're copying the design generously shared by team 2073 (see this thread: 2073 Pneumatic Catapult

We'd like to control the cylinder supply pressure with a proportional control valve (aka I/P). Has anyone done this.

In the past, I've modified a regulator by changing the diaphragm spring and replacing screw with driver rod: illegal for FRC. Here's an idea of how to adjust a regulator via a servo without directly modifying the regulator (see pic below). Would this be allowed?
