If you are currently firing electric to cone 10 and are not firing the kiln down (slowed, controlled cooling), then before I'd look at the impacts of adding reduction into the equation, I'd try the firing down idea. More of the effects that people assume are from reduction in big gas kilns are actullay from the effects of the larger thermal mass, the better insulation, and hence the slow cooling.
There are tons of considerations, but if you don't increase the insulation on that kiln shell....... you'll get the same fast cooling. And the kiln structure and load will have the same thermal mass as if it were electric fired.
The weed burners also are a bit problematic to use.
More info on your goals might be very helpful to allow people to comment accurately.

However, that may be all your budget wil allow, right now anyway. I have the M750 from Ward, and it really puts out the heat. If you could get the dual burner system , you will definitely be set, but I think that will be overkill, the guys from Ward will certainly be happy to advise you; Marc Ward himself helped me, and I'm a nobody.
Anyway, bore your holes for the burners, one in the lid for the flue, get lots of propane, and let it rip.
Try it. You will learn alot; it may not work on the first try, but make corrections and go from there.
Don't be dissuaded by those who say YOU CAN'T. (Not that anyone has said that, but you will find some, I bet.)

I've been given an old electric Skutt, 1 size smaller than the 1027. I'm interested in removing the elements and adding 2 weed burners for cone 10 reduction. I'm in need of advice on converting and firing. Thanks much, Dorie
Seems to me that a company makes the type of kiln you are talking about building with your conversion. I think Olympus did it- at least in the 90's. I'm not sure about now. I think you should try it out and see what happens. You may learn quite a bit from the experiment!
