It should be fine I think. On Linux you can have multiple Desktop Environments installed (ex KDE Plasma & Gnome as well.)
I tried Hyprland a few months ago like this. I had Plasma installed then installed hyprland as well. During login with SDDM you can select which DE to launch.
Edit: On github it says you should install it alone to make sure. I dont know then, maybe it works? I am still new to Linux as well.
