That's a great idea!

Most likely I'll use those slot widgets to change different profiles for Xbindkeys.

I tend to use Quickswitch the most.

But the hardware keys sometimes need to go back to default when playing music.

I also have a setup for right clicks to be used with SCUMM and Dosbox.

So yeah, this will definitely come in handy for me.
