Hey :)
I just wanna let you know I built Ubuntu ISO image with integrated COSMIC DE, which is building on my PPA: https://launchpad.net/~hepp3n/+archive/ubuntu/cosmic-epoch
Currently updating to epoch-1.0.16. The debs are directly from upstream, rebuild on launchpad with amd64v3 enabled (not recommended tho).
The iso have baked PPA for updating DE binaries. Ubuntu/GNOME sessions are removed with most of the GNOME packages.
The experience is nice, if you like Ubuntu and COSMIC it should fit your needs ^^
