I've made some slabs in the 30X60 cm range. Not perfect, but no
serious problems, either--they didn't crack in half, for instance. Paperclay
if slightly overfired will lie down on a shelf when hot, even if it warped
while drying, and I have used that to advantage.
So I say build your big wide shallow kiln. The one I've used to fire
in is two shelves long by one wide. I've also done one piece in a wood-fired
kiln on two shelves leaning against a stack of bricks. That worked fine too.

Good luck,
