arran4 , 2 days ago Using Gentoo might work if you enable the KDE overlay: https://wiki.gentoo.org/wiki/KDE/Ebuild_repository Gentoo supports slots; which allows for concurrent installations of things like desktop environments. Not sure if it's configured that way right now though. If you use BTRFS you could install gentoo on a subvolume and boot into it when needed too.
