Comprehension: He is not asking about different width tires he is asking about different diameter wheels and tires. If it were a simple matter of width there would be no question as all you have to do is play with the sidewall size to make everything look right.
Math: Now Lets just say you take a truck that the rear is stock 2" higher than the front. It would work something like this
Front 0 Rear +2
Rim 18 Rim 18
Front 18 Rear 20
Here we still keep the rear 2" higher than the front. Now to my next demonstration
Front 0 Rear +2
Rim 18 Rim 20
Front 18 Rear 22
Now my fingers tell me that 22-18 is 4 so the rear would sit 4" higher than the front except that 1" of the rim would be above the axle and would be absorbed into the wheel well. If you wanted things to look right and kept the sidewall on both the front and rear tires as close to equal as possible. Now you could get around this by running a 60 series front tire and an 45 series rear tire. Bare in mind that on a 275/65/18 tire there is roughly 7" of sidewall on the tire, however on the 275/40/20 there would be only 5" of sidewall which would look a bit out of place.

The top of the tire, yes... the measurement to the bottom of the bumper, inside of wheel well, top of bed, whatever, no. Hence the rear will not sit 4" higher, it will sit 3 inches higher given the same sidewall on the different tires because that additional 1" is just absorbed into the wheel wells just like you stated.
If I had time, I would make you a very pretty illustration on this CAD box but I don't. Trust me on this one.

Appearance-wise, it's not all that bad of an idea.
The ride quality would be kind of messed up.
No matter what the specific measurements would be, you'd have little rubber on the rear and more up front. That would make for a rather stiff ride on the rear... not very fun.
