Setting Element Parameter to Formula

In this script I am trying to set the voltage parameter on an electrical connector in a family equal to a shared parameter “AAI Equipment Volts”. When I use the Element.SetParameterByName node I run into the issue that you can only input a number and not set a formula equal to another parameter. When I try an use the Formula.Set node I run into the problem that it needs to work inside a family document, I can’t do this because an electrical connector is just an element, not a family. Open to any suggestions. I need to be able to use the script so I can run it on a large number of families.

Did some more playing in dynamo, could I use the Parameter.Associate node in the Orchid pack?
