Just keep in mind the 3.6 and NAG1 auto are really good together, but the actual performance is still dependent on the diff gear being right for the Tyre size.
I have a Rubicon 2-door which is slightly lighter. 4.11 gearing has worked well with bigger tyres. 3.27 diffs and 4-door would make it feel underpowered.
