Nissan engineers thought the VQ37 engine ran hot too and in 2012 added a cooling system to the oil and added a larger pressurized coolant tank like the GTRs have. My '13 has both of those mods and my temps run about 200 in DD and as high as 220 when I push it in the twisties. Of course I live in the PNW where 80 is the normal summer temp. 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.
