Add AGO webmap operationalLayer JSON to an already created map object

Hoping someone can help.  I have a map where I use utils to createMap from a webmap JSON file.  Later, I want to add other layers that come from a config file that has all the properties of an operationalLayer.  Is there a way to add an operationalLayer to a map?

Currently, I'm creating a second map, grabbing the layers and then map.addLayer()-ing them into my current map.  While this works in some cases, larger more complex layers it hang/errors.

What I want is to be able to easily configure popups/visibility/opacity through JSON, and then as the user wants, bring these into the map.

Ideas? I'm struggling!
