Interesting idea...
Typically, a smaller diameter, longer intake tract is beneficial to low-end power, at the expense of high rpm torque/horsepower.
Exactly in rpm range you'll be cruising at.
If your Jeep uses a MAF setup, be careful your smaller TB assembly isn't part of the intake where your MAF is located. In otherworldly, if you use your MAF sensor in a smaller diameter housing, you will seriously mezs up your fueling, as the ECU determines the mass of the air flowing thru the sensor based on the fact that the air is also traveling thru a certain, and known, intake diameter.
If you're going to go this far, I'd also check the intake manifold for velocity stacks...
You can also shift some power down low by using longer stacks.
My one car runs a ECU controlled, duel stage intake...at 5000rpm, it switches from long tube stacks to shorter ones...and you should hear the difference when it happens To WOT!
