I did it on my Audi. Generally pretty ineffective, and those SPAL fans are Noisy. In addition, the fan blocks a lot of the flow through the cooler, so it's less effective in general.
Personally I'd skip. With a correctly sized cooler you can run 3/4 of the year with no block-off, then just slip it on for the winter. The cooler install on my Z worked just fine this way..
Without a cooler, 220 degrees is a normal temp on this car....Nothing to worry about at all and no need to introduce additional cooling efforts, expense and complexity....
