Adding a Custom Legend Entry

I want to be able to add a custom legend entry that is a color ramp for a unique value renderer that is calculated off of a color range. I have several zip codes that are color coded based on a series of related values. Though the values are distinct in the renderer, they all come from the related ramp like that pictured.

I think I might be close to success with the following code recommended by @RobertScheitlin__GISP, but ultimately the dom is re-rendered and it disappears.

watchUtils.when(legend, "container", function() { aspect.after(legend, "scheduleRender", function(response) { legendEntry.appendChild(legendTitle); legendEntry.appendChild(legendRow); legendRow.appendChild(legendRowSymbol); legendRowSymbol.appendChild(rampRow); rampRow.appendChild(rampHolder); rampHolder.appendChild(colorRamp); legendRow.appendChild(legendRowDescription); legendRowDescription.appendChild(labelHolder); labelHolder.appendChild(lowLabel); labelHolder.appendChild(highLabel); target.appendChild(legendEntry); }); });

Does anyone have any ideas how to get some extra elements to show up in the Legend widget without completely rewriting the widget?
