The current approach with moly's has been to keep the chamber as tight as possible so the pots almost hit the walls. Passing the elements down towards the floor makes that space too small. The elements should ideally have about two inches clearance from the pot.

I have read your third sentence three times and do not understand it at all.

The area above glass line is pretty much dictated by the size of the door opening. That casting needs some structure above the opening or it will collapse.

This is really only a problem on the 28 inch and 34 inch sized furnaces. It has been worked around with the heating of the foot of the pot. My 28 inch has these problems and I just go slowly. I have never lost a pot in a moly furnace.
