So how much difference in tire size is considered a mismatch?  I have
27x8.50-14s all around and the spare is 205/70x14. According to my tire
calculator that's a difference of 1.63" between the two.

Fuel economy, you do loose about 10%. 16 to 18 mpg is about normal.
Tires, you need to maintain a matched set. I use 5, rotating the three on
the right side as the right front seems to wear the fastest. If I have to
replace 1 or 2 I place the new ones  one front-rear to keep the axle speeds
matched.
