I could easily do without two-meter capability on the KX3.  About all I
(rarely) use VHF or UHF for is FM mode, and I like to be able to use that
independent of what the HF rig is doing.  In any event, I'd still need
to carry an HT like the extremely small Yaesu VX-3R to have both two-meter,
70-cm, weather, and public service frequencies covered.

I see internal batteries in anything like a K1, KX1, or KX3 as having nothing
but novelty value.  (I removed the KBT1 from my K1 after a year of use.)  In
something like the unfortunate Yaesu FT-817, it's the height of foolishness.
Any real period of operation will require at least an external 4 AH SLA battery.
I'd be *very* happy if no internal KX3 space was wasted accomodating internal
batteries.  Put other options in the vacated space.

Well, I have to say, the possibility of putting options in the battery space, making the internal battery an option, appeals to me too.
Then a good 2m transverter could go in the battery space and still be room for the ATU, might even be able to put the 100w PA in place of the battery, which seems to make sense, since the internal battery wouldn't last long with a PA

Unfortunately, no. The KX3's normal low-pass filters are rated at 15  
W, as is the ATU.

The battery is very important; it makes the KX3 an all-in-one unit  
that you can quickly deploy in an emergency, take on a short hike,  
toss into a very small small corner of your suitcase, etc. It's an  
inherent part of the product.

This is exactly what I have wanted since the KX1.  I own the FT817 and the
battery issue is just that... an issue.  With 6m SSB and all the low bands
in the KX3, it fills all I could ever hope for in a portable, especially
with the planned add-ins.  Plug in units in the battery compartment could
serve as additional add-ins to make greater flexibility for future updates
which the user could purchase.  I have enjoyed the portable operation of the
FT-817 with the options of additional SSB filter and DSP along with the
latest NIMH battery technology, but I would abandon this in a moment for the
KX3 design when successfully implemented.  Having 2 meter FM is not my
requirement.  I have a TH72d and TS2000 for playing around and the TH72d
takes care of my VHF UHF needs as a portable station including APRS and
Packet.
