Just to answer a couple of things. First, all cells in the 1803B are identical. It's their configuration that makes them seem different. Second, as already mentioned, the 1803 is massive even in comparison with the 1505. The 1505 is probably better for home use but if you really want to be crazy, I'll see if I can find a way to measure the 1803's so you can do a take off. This will not be easy as they are hanging in the speaker room so if you say yes Audiomind, I want you to promise you will build them. I would love to see another build thread. The Petter Persson thread over at diyAudio was absolutely fascinating. His method of using rings that he slid down the horns to act as clamps was a stroke of genius. The finite detailing at the throat must have taken an incredible amount of patience. That was true craftsmanship. My hat was off to him.
My idea would be to make a pattern of one cell cutting out some sort of separate thin cardboard for each side of th inside walls. (maybe something like the large white foam sandwich pieces you can get at a craft store that go behind picture frames).

But the real challenge is the throat. I am sure there is an easy way to make a copy with some sort of casting materials that could be put inside.

Unless the guy on ebay will come down to $2500 from $7000 I am building them myself so that is a guarantee, they will be built, they already have a loving home.
