OP, why not add a 25 row oil cooler and run with it that way in the summer. Then fab up a sheet metal block off plate and put it over the cooler in the winter? Blocking off the cooler in winter would prevent overcooling.

PS: If you don't get a winter beater to drive, at least get a good set of winter tires. Trust me, you won't like the summer tires on frozen roads. But you probably already know that being from Chicago.
