Has anyone replaced the engine driven fan on a w126 with an electric puller fan to increase AC performance?

The AC on my 89 300SE was converted to r134a before I bought it. I've further converted to Dura Cool refrigerant which improved it, keeping me nice and cool as long as I'm at highway speeds, but it still struggles to keep the interior really cool when the outside temperature is above 85 and I'm in stop and go traffic. I'm tempted to try it, I just wondered if anyone has any experience with such a conversion and if it did improve AC performance in stop and go traffic.

Thanks.
