Absolutely this is worth packaging for KDE.
Although I imagine if you don't have the motivation to make it in the first place, you likely don't have the motivation to package it.
I've got Opus crunching on it now, will update when I have it finished and published

Running on my Fedora KDE machine right now. Also includes a CLI so you could wrap your own widget
I still need to figure out publishing, doing this in between work meetings.
I am happy to package it and port it for Gtk/GNOME today.
I feel like this is so lazy bothering maintainers for it is not great.
