Just consider the battery as part of the "frame" on the K4.

Ok, so here's what I ended up doing:
I disassembled the K4B and replaced the motherboard (more on that later) with another motherboard from a used K4B I had laying around: profit! Worked like a charm.

Now, before assembling everything back together, I disassembled another K4S from my son; result: no go.
You cannot switch motherboards/displays between K4S and K4B.
So, a few notes on my experience assembling/disassembling K4s (I assume you've all seen the video posted above, so these below are a few comments to consider if you want to venture):
- Be careful not the scratch the rear cover of the Kindle; the plastic is soft and prone to dents.
- Avoid putting too much stress on the kindle as you pull off the clips of the rear cover. You will break your screen. Can't stress this enough.
- As shown in the Youtube video, start with the bottom right side of the rear cover and then pull off the two bottom tabs. Move to the top two clips on the sides and remove the top two tabs.
- The glue that binds the rear cover to the battery cover is sticky/hard as hell; Using a blow dryer to heat it up did help a bit.
- By the way, you will break part of the four plastic clips that hold the rear cover to the kindle. Don't worry; everything clips back in place once you're done; not noticeable at all.
- Removing the top bezel was surprisingly easy; start with the bottom right side (pry it through the Page Next Button with a plastic tool)
- Now, the scary part: removing the motherboard... oh boy, the thing is stuck as hell; it is glued to the kindle's frame. Again, warm the board (and thus glue) with the hair dryer. As you pull it out, be careful not to dent the kindle's frame. It's a bit difficult but doable.
- One last comment: before removing the motherboard, remember to first pull off the ribbon that connects to the battery (then the other 3 ribbons); upon assembling everything back together, make sure the battery ribbon is the last one you connect.
Hope this helps other users.
