Irritrol OMR100

I'm looking to reduce the pressure on a few of my old Greenlawn valves without the hassle of replacing them. The old ones are still working fine and the box configuration is a bit wonky so it would be a PITA to change the valves. Some companies make pressure regulating stems that attach at the solenoid port, but their size and thread patterns are not interchangeable with the Greenlawn valves.
Irritrol makes the OMR30 and OMR100 pressure regulating stems which appear to have a similar thread pattern. Does anyone know if the Irritrol solenoid is interchangeable with Greenlawn, or even Orbit? If Irritrol and Oribt are interchangeable, I can buy an Orbit solenoid at HD and see if it fits my valves to know for sure before ordering.

If you want to reduce the outlet pressure on a Greenlawn valve, the one sure method is to swap the standard valve cover to one with a flow control.
