I do include CDE and Open Look (the window manager and toolkit, at least). In both cases the add-on tools that were present in Solaris (like the whole of the DeskSet suite) aren't available, because they were never released in source form.

But there is a 64-bit port (which I ought to bring in to Tribblix)
I wanted to run olvwm on Linux (when it went out of support on Ubuntu 16.04) and I'd managed to get this running on Ubuntu 20.04 (and more recently on Gentoo, as documented at https://ces.mataroa.blog/blog/gentoo-olvwm-bye-ubuntu/).
A survey of available olwvm implementations available on github at the time I created the repo is in the README of https://github.com/olvwm/xview/
Currently this works on an ancient 32-bit laptop (running NixOS 22.05 as documented in https://ces.mataroa.blog/blog/distro_hoppingmd/) as well.
And thank you so much for tribblix; I was about to give up on illumos after repeated trouble installing OpenIndiana on my laptop (Tribblix worked out of the box on the hardware). I’ve since picked up a copy of “Solaris Internals” and have spent some time appreciating Solaris. Kudos.
I would expected CDE as a first class citizen and maybe OpenLook.
And it says that it it maily for 32bit SPARC and 32bit X86 and later that "Important: 32-bit hardware support now completely removed.".
