There is enough room to engrave the letters and numbers, and as you can see it is enough with just 4 letters per word.
I'm not a big fan of omitting "error correction" by leaving out characters. Any chance you can share a picture of a washer in it's final look? I get a feeling it's going to be crowded on there.
But I do like the compact seed phrase

I do not like it either... but... if it allows me to fit a whole seedphrase in one washer, it might be worth it (there are also many recovery methods that also rely only in 4 words, even cryptotag thor which costs like 350$...)
It is indeed crowded, but not that much, quite "readable" and the letters do not overlap. I will try to upload some pictures over the weekend
