@Deceptichum I had three identical plates made, though one I modified very slightly. After accepting that I'd need to simply live with a split Left-Shift, it's been extremely usable.
Build 1 was BBC Micro inspired and is a simple flat sandwich with oak sides, DSA on the FRow, a Dolch-like "VSA" elsewhere, and Box Navies. This may still be the one I like typing on the most.
Build 2 was pre-lubed brown TTC, sloped 3d prints for the left and right, and stiff springs in the middle. In effect the entire board is a leaf spring. CSA keycaps from Amazon. This one has the double shift adjusted (courtesy of a dremel and a metal file) to be in line with what the ISO layouts do.
Entire writeup with pictures of all three are on my geekhack thread. They're all a little too rough around the edges to make sense as anything other than personal projects, but they are usable and do have their charms, and I love building these things from scratch.
