You can put an ARB locker and 35 spline shafts in your current housing and end up with a rear axle that is better than the Rubicon axle. My rear axle build cost about $2k without labor and is described in my thread below.
Or he can save a a few hundred dollars and go with a Yukon Zip locker, which is an air locker very similar to the ARB.
Personally, I would not install an axle with an incorrect ratio on my Jeep. Essentially, you are making it a two wheel drive. If you do have to do it for whatever reason, then I think you can leave the front drive shaft safely removed, that way there is no possibility of forgetting and putting it four wheel drive and tearing everything up.
