What I ended up doing...

I ended up destroying the old child (gtk_widget_destroy(child)) which removes
the child from the container, and destroys it.

I then add a new child to the box (gtk_box_pack_start()), and then reordered the
child to it's rightful place.

And the way I managed the child, is with a g_object_set_data() to store it's
address, for accessibility (which brings up another concern, but that's the
subject of another thread :)

Thank you all!
