I have accomplished something similar to this in the past by utilizing Appian's externalize() and internalize() functions.

Steps:

Use externalize(rule!someExpression)
1. Do not put the parenthesis for your expression in this function
Store this string in your CDT to reference later. For this example, I would store it in ri!softwareCDT.externalizedString
To call this expression: internalize(ri!softwareCDT.externalizedString)(input1: "ABC", input2: "XYZ")

This should execute the rule reference you have stored as a string in your CDT.

There may be some extra challenges you face, but this is the basic concept.
