I'm suggesting to add Enlightenment to devuan. It's fast, accelerated, beautiful, innovative and use very low mem / resources. :) Maybe from source files (can be compiled --without-systemd) or maybe patching / working on Neko2040 ppa repository - I used them a lot, they're very well built! https://launchpad.net/~niko2040/+archive/ubuntu/e19 for details. Also, E is a lot better than xfce ;)
