I think I've finally arrived at mine. Looks strange, but doesn't feel strange. The most recent changes were to cut the graphic symbol keys from 18 to 15 (they still have Shift and Ctrl and Alt states) to make room for PrtSc/ScrollLock/Pause which in turn pushed the Greek and F-keys to the left by one. At the same time I reorganized the number/cursor pad area. I might have to tweak it again considering I'm finding software that doesn't accept Insert and Delete from the number pad, only from the cursor block and those two keys are absent here. (I am faking it with AutoHotkey in the meantime.) Now that the number pad is relatively normal, I can use the standard (non-lensed) keys for it which feel much nicer.

In addition to the matrix-Dvorak layout, I have booted [{ and ]} out of the top row, moved =+ back to its normal QWERTY location, and thus reduced the width of the matrix from 14 keys to 13. The trade-off is that the [{ and ]} keys now have to reside in the lower right corner amongst the modifier keys. I do use them enough that I will not force them onto AltGr or anything like that. (Lots of forum software requires them in place of pointy brackets.)
I wish I had the version without the trackpad, but those are always well over $100 and I got this 63401 for under $60. The big dead space sort of forced my layout to the top in order to also let it move to the right, but it turns out that this is a very practical placement anyhow. Now my macro keys are under my thumbs, which is really convenient when I use them in games. I don't think I would have ended up with them there (at least not nearly as quickly) if I had been able to lower the alpha area by one row as I originally wanted.
