Is this a good idea, or should I just keep the Cetrek for a rainy day?

Your idea will work fine AFAIK.
You say the old Cetrek pump was previously used on your current
Check that the Cetrek pump hard over time is within the requirements of the Ray pilot-normally 10-15sec.most pilots.
In most cases,pumps don't care what brand of a/p electronics
drive them & a/p elec. don't care what brand of pump they drive(as long as HO time is within range)
It is good practice to have isolating valves in your pump lines anyway-you will appreciate them first time you have to service/replace the pump.
