That should work. One of the benefits of Wayland is that it's better at scaling than X11. What version of KDE are you running? Is there a switch between two different types of scaling (one is blurry for XWayland applications but works for all of them, the other is sharp for all applications but only some XWayland applications and all Wayland applications work)?
It would be largely fine, but be careful. Being immutable, a lot of things that you would expect will work differently or not at all. I would not recommend it, but if you're in for a challenge, it's not bad.
