Comment (by westonruter):

 Yeah, the problem is that all widgets instances are registered during
 `widgets_init` up front when WordPress is initializing, so doing
 `switch_to_blog` is going to indeed switch the `sidebars_widgets` but then
 it is going to be referring to widget IDs that are not registered. I
 suppose you could try re-running `do_action( 'widgets_init' )` after you
 do your `switch_to_blog()` call, but no guarantees. There's also the
 problem of needing to re-initialize `$wp_reigstered_sidebars`; see

 An alternative solution was written up by WebDevStudios, which involves
 using Ajax to fetch the widgets from other blogs, though the widgets could
 be fetched server-side via `wp_remote_get()` too of course:
