I would say yes. I got an MPG boost on my Metro by swapping in a higher temp thermostat. I live in a cool climate, so there's nothing but gains to be had out of running warmer.
You could also try messing with your temp sensors...on older cars, at least, it can make them run leaner/more efficient by tricking them in to thinking they're running hotter. Probably not good for emissions, though.
