[Elecraft] Internal AAA batteries for KX1?

FWIW 
I use Lithium Ion batteries in RC planes and I also use them with the KX1, K1 and other rigs. However I do not use them in the rig, I have seen too many battery failures over the years (30) to trust charging in the rig. I do have several 3 cell (11.5) volt flat cell packs I use as external source. I like this as I can change packs on the fly and charge them away from rig. As an example a 3 cell flat pack with a rating of 3500 mah is about the size of an 8 cell AA flat pack but thinner and about 1/3 of the weight. They do require a charger that is made specifically for Lithium Ion packs. I carry 2 of these in back pack and get many hours of op time before needing recharged.

I have a rechargeable lithium CR-V3 battery for my digital camera-it is 3V
nominal, and the same size as 2 AAs smushed together side-by-side.  The 3+3
cell arrangement in the KX1 precludes using these, but I wonder if someone
is going to come out with a rechargeable lithium AA-or do they already
exist?

I saw a posting yesterday on QRP-L where someone saw AAA Lithium batteries
for sale so I went to the Energizer.com site and sure enough it looks like
Eveready is now manufacturing a 1250 mah AAA Lithium cell.

This got me to thinking about how great it would be if Elecraft offered
an alternative bottom cover for the KX1 that had 2 X 4 AAA holders giving
12+ V instead of 10V with the 2 X 3 AAs.
