Would you mind testing if replacing the following also works with Orca?
(sorry, I don't have a setup where I can right now)

QWindowSystemInterface::handleWindowActivated(w)

We ideally don't want to risk changing anything on the X stack there's potential for side effects, and it won't work at all on QtWayland.

I believe this is the important line that your code will be triggering which we can call directly.

This is problematic: KWin cannot activate it's own windows and trying to do so is undefined behavior. We need a way to have this working without going into the API which will do X11 stuff as David says.

Use qpa api instead of actually requesting the window to be activated.

Thanks for coming up with the idea :) Now it will be just the second part... figuring out a nice way to trick the qml parts to have an active focus around.
