The safest way that you should start with would be installing kubuntu-desktop metapackage, removing ubuntu-desktop metapackage and performing sudo apt autoremove --purge after reading through packages that will be removed and verifying that you don't need any of them.

However if you have limited space you can remove more packages that you don't need and that action may remove kubuntu-desktop in the process. At that point you need to mark some packages as installed manually to avoid removing them when you perform autoremove. You can do it either with apt-mark or just by performing apt install packagename.

Another, less safe way would be finding a package that all GNOME software depends on and removing it so that it will take all the packages that depend on it with it. libgnome-desktop-3-* looks like a candidate package for that. Be careful around libgtk* packages though as it may be too excessive, kde-config-gtk-style and kde-config-gtk-style-preview depend on it.

Before starting you can backup lists of installed packages with apt-mark showmanual and apt-mark showauto.
