Kellogg (JD/MBA) vs Fuqua vs McCombs (with scholarship)

I might be biased since I got accepted at Fuqua, so take what I say with a grain of salt. I absolutely love Fuqua! I believe Fuqua's energy finance and energy & environment concentrations provide a unique edge for any MBA student with interest in energy. No school in top 15 have concentrations geared towards energy (except McCombs perhaps). If your goal is to enter VC and focus on energy, then no doubt Fuqua is the place.

I intend on pursuing a dual degree when I am at Fuqua (MBA + MEM). I was told that once you are at Fuqua, admissions will give preference to their own. For instance, if you are at Fuqua and apply to Duke's JD program, you are bound to have a leg up (even little bit) in the admissions process. Not sure if you are aware, JD and MBA buildings at Duke are 30 sec walk from each other. When you compare that to Kellogg MBA and JD buildings, they are fairly apart (I believe their JD building is in downtown, which is far from the MBA building). If you want to go for a sure thing, since you have already been admitted to Kellogg, that might not be a safe bet.

Here is my quick thought processs:

Energy (education wise): Fuqua > McCombs > Kellogg
Energy (location wise): McCombs > Fuqua > Kellogg
Brand: Kellogg > Fuqua > McCombs
Location: McCombs > Fuqua > Kellogg (I am assuming that Evanstan winter is not fun to be in!)

What doors would the JD open that wouldn't open otherwise? Outside of law firms and a few investment shops specializing in highly regulated fields (think health or energy), I don't see the value of getting a JD in addition to an MBA. If it's just a mean to get a law education, why not take a few courses at the law school but not complete the full curriculum (and thereby saving yourself $$$)? Otherwise, the cost of adding those 2 letters to your resume far outweigh the benefits, very minimal in my view.

Question: can you take the JD/MBA admission offer and drop out of the JD?
