The effect on those translucent caps looks pretty nice, although it would be *dox.
The RSTHD layout was originally designed native to the Ergodox which is comparable in size to the 01/100 family, so it would just be a case of porting it across more or less. Much easier than me adopting it on the Minidox. The Atreus would be a great learning experience where I could take what I learnt on the Minidox and just give it a little more elbow room.
I couldn’t resist sharing this chart on the RSTHD inventor’s page, showing comparative efficiency compared to other layouts (according to his own assumptions used to evolve the layout, of course). My experience confirms the uncanny lack of physical effort involved even though I am still having to think what I am doing:
Here is another layout with a thumb pressed vowel - ‘I’ this time. Whilst I don’t know the letter layout, perhaps some of the layers are instructive to what we might be trying to do?
Finally, I am running a poll over on Deskthority asking what layout people would learn if starting again from scratch. I see there is a poll function on this forum, maybe we can look at one here sometime?
