In terms of a low profile portable design, perhaps a chimney-less
updraft would be possible. The chimney is much more likely to
attract attention than a box. People get all weird about chimneys.
Use the power of the gas to push, rather than a chimney to pull.
Perhaps having a sort of "sutema" would be of use to increase
efficiency. In an anagama kiln, the sutema is literally the "wasted
space" -- it's a small chamber behind the main body of the kiln which
serves mostly as a place for the fire to slow down a bit and leave
some heat behind. The sutema clips the kiln temperature fluctuations
that come with stoking to some degree, and provides a more even and
stable temperature rise in the main body -- at least that's the theory.
So, in your fiber kiln, imagine an exit hole in the roof that
exhausted not into a chimney, but into a smaller chamber about 1/4
the size of the main chamber, and from there it traveled out another
exit hole or holes into the atmosphere. Probably a good idea to
offset exit hole(s) to make the fire play around in that space a bit.
Anyway, it's a design idea I've been curious about because I want to
build a summer kiln (I only fire the anagama in winter), and frankly,
I'm bored with my raku kiln. I want to do wood though, so fiber is
pretty much out. Actually, I want to see how much of it I can make
with just dirt. Dirt is really cheap.

I can offer you plans to make a C10 "updraft" 12 cu.ft. kiln which uses
ceramic fiber for insulation.

expanded metal gas kiln with angle iron
I am returned to taking a sculpture welding class and now have
access,materials and instruction to make a kiln.I have shelves and burners that are
portable since they are on welding hoses that detach after firing so I thought I
would build a gas kiln on wheels that I could draw up on a come a long to my
open trailer and transport to sites where I could fire it.
One question I forsee is how to make a chimney for it if it is downdraft run
on two blower propane burners that have Ecipse preheat burners piggyback? I
also wonder how thich I need the fiber to be so it will reach temperature
without compromising the steel frame.I am using the 12"" x24"" silicon carbide
3/4" or 1''{forget which] shelves stacked 3 deep, 1 wide with flame path
coming from 2 low rear sided ports using a target brick of a hardbrick to turn
the flame.
The door may need some engineering but my present brick kiln that I am
trying to copy in fiber has a brick up door that comes up just touching the kiln
shelves on their outter side.I have a port to the chimney at the lowest center
back of the kiln floor in my present sprung arch hard and soft brick kiln [
floor, posts, burner port and chimney and flu and exterior, save the door hard
and interior soft brick Eclipse 23 and 26,where appropriate, A.P.Green
varieties].My brick kiln is dryset and was designed with a bolted frame.
The brick kiln fires like a dream and has a chimney height of just 6 feet
so it does not stand out in the suburban homesite and is close to 5 ' tall the
kiln itself.The soft brick arch has a fiber blanket cover and a transite lid
for rain protection, warm climate here. I am hoping a fiber clone of that
kiln on wheels could utilize the same extra shelves but am open to any
suggestions.

My friend doug black has a high fire bell kiln he uses for hikidashi
(pulling out pots at high temp for seto guro/black.)
It is an updraft and the top is on a counter weight.
