After now using the system for a month+, a couple suggestions for DJI for your next iteration of the adapter/charger.

a) Formally support charging the battery and the controller at the same time.   You have the wiring, but in the manual you specially say don't do it.
b) Add at least 1 if not 2 USB 2.1a Charge ports.    This will allow us to charge our tablets/phones that we use on the controller, all in one swing.

I have seen some third party, "multi-battery" chargers.   
I would love to see a formal 1st party one, that is smart and can be adaptive.

I can see when I have 3-4, or more batteries, the need/desire to charge them all one time.

Good ideas!

Here's a product that'll be available soon:

It's pricey, but it'll do what you're suggesting. Also, we might see a charging hub from DJI at some point since they offer it for the Inspire 1 now:

Only the $489.95 one seems to charge them all at once. The rest, even the DJI one for the Inspire, charge one at a time still. So it will still take 1 to 1.5 hours each battery.
That $489.95 one seems to also charge your phone/tablet and 2 RC's. But wow almost $500!

Nice looking product, but it is on the higher end of the price range.
I could purchase 3 more adapters at $180, power strip, and usb adapters for another $20-$30, and complete the same at just a little over $200.
(Not saying it would be as nice and compact, but it would function)

Then products like these:

Are starting to show up more and more....  $20-$30?
