That should also be better than the tandem radiator setup. How does it
behave in warm weather? Can you fly normally in temperatures of 35 degrees?

Well, you could achieve the same with a cowl flap I think.

The reason I don't like thermostats is that you will still have the
cooling drag, due to dragging air through the radiator, while you
actually don't want to cool anything.
With a cowl flap that closes off the air flow through the radiator, you
can also prevent overcooling, but at the same time you reduce drag.
