Steve, have you used this method of "in the bottle" force carbonation
chamber?
In theory, it should work. In reality, I don't know. What happens when
the corny is opened? You gotta cap them, fast.
My guess is, yes, you've got to cap them fast, but as long as you do
that quickly they will remain CO2-purged and oxygen-free. When they are
suddenly reduced back down to 1 atmosphere of pressure, the liquid will
immediately start giving off its excess dissolved CO2, thereby
preventing the introduction of oxygen. But the tiny surface area in the
neck of the bottle will not allow that to happen too quickly, which will
give you a little time. Presumably you're good enough at bottling to cap
6 bottles fast. If some foam develops spontaneously, all the better -
the bubbles in beer foam contain pure CO2, and a cap squished down over
foam is making an oxygen-free seal.
One thing that might help here is to have ice water in the bottom of
that corny keg, and set the keg itself into a bucket of ice water, to
make sure the bottles stay as cold as possible until you actually cap
them. That will slow the release of the CO2 you just worked so hard to
get into them.
It might be more interesting to experiment on this kind of thing with a
beer that is not your every-drop-is-precious eisbock.

At what temp/pressure are you setting these at?
I'm guessing I would go
something like 20 psi, knowing it would never hit that in the bottle,
for a week at 34F, hoping for a 10-12psi result.
I would still probably move the uncarbonated beer into a cleaned,
sterilized, and purged with CO2 corny, then use the CPBF (counter
pressure bottle filler) to deliver the beer to the sterilized bottles
as part of the CPBF process is to purge the O2 with CO2, then put the
uncapped bottled into a cleaned, sterilized, purged corny.

I tried a variation. I did the plastic jug but
then collected the
resulting liquid directly into sanitized bottles. I then placed the
uncapped bottles inside a CO2 purged corny keg at the appropriate
pressure - I'll remove them later this week to cap the bottles. I am
not sure this is going to work but figured I could end up with more
beer this way since I won't have worry about loss via the counter
pressure filler when I only have enough liquid for a very few
bottles.
You can get around 6 bottles to stand up inside a corny, use some
empties if necessary to keep the full ones from tipping over.

If you freeze a sanitized plastic water jug 3/4

achieves the purpose.

(If the container happens to be a corny keg, then
your beverage can

carbonated prior to bottling...)
