I can go up to a 185/60/14 and keep most of the spedo difference in check at .09% difference but the tires will get heavier and 1.1" wider which might reduce my efficiency/MPG and raise rolling resistance, un-sprung weight and other factors??

What I found is the rear wheel well is the ultimate, size determinant. As an experiment, buy one wheel and tire and then mount it in the rear and later, swap it in the front. You won't be driving far as much as taking measurements and then looking for a 'speed bump.' You want to make sure there is no interference on a bump or problems at steering limits.
GOOD LUCK!
