This is a hard part...

That's how I'd implement it. Just query the list of object args, save the
current value of each; then reconstitute from the saved arg values. I
don't think you need a Serializable base class, just say that if it's not
exported as an arg, it won't be restored.

This is easy if you can do 1) ...

I'm sure you'll end up hacking on Gtk internals a bit and requiring people
to use your new improved Gtk version to get this to work. But it's not
totally impossible to do, I wouldn't think.
