There's no method to do it directly, but it's not hard to write one,
e.g. (untested)

static void ReplaceWidget (Gtk.Widget old, Gtk.Widget new, Gtk.Box box)
{
    int pos = System.Array.IndexOf (box.Children, old);
    if (pos < 0)
        return;

    bool expand, fill;
    uint packing;
    Gtk.PackType packType;
    box.QueryChildPacking (old, out expand, out fill, out padding, out
packType);

    box.Remove (old);
    box.PackEnd (new);
    box.SetChildPacking (new, expand, fill, padding, packType);
    box.ReorderChild (new, pos);

    new.Show ();
    old.Destroy ();
}

Alternatively you could use a Bin-derived container (i.e. contains
only one object) as the placeholder, but that would be unnecessary
overhead.
