Sometimes when I've needed a non-round lid, I've filled the pot (barely
leatherhard) with vermiculite until a mound formed, then laid my slab over
it. Not saying this is better than your method....but you can set a thrown
knob on the top too. The bottom pot would not have a gallery. When the lid
is soft leatherhard, I add a coil of clay a little ways from the edge.

I use cheesecloth as the mold itself when I am slumping lids for oval
pots.
I drape the cheesecloth into the pot and slump the lid into it. Then
I take it out when it is stiff and shave to fit.
