How much of a MPG bump could I expect from doing this, though? For 1/4 mpg I'd rather have power steering. For 1 mpg, I might do without.
There are a few easier things you can do to a Cherokee to get better MPG.

1) Get rid of the mechanical fan on the passenger side and replace it with an electric fan. Taurus electric fans are pretty popular for this

2) 4 hole injector swap - there are direct swaps from certain Neons and some Ford injectors can be used.

There's also the option of using an A/C clutch on the PS pump, I believe someone here did it on a Ranger
