I'm not sure because I don't have time to test it, but try calling wp_widgets_init() like so:

global $switched;
switch_to_blog(1);
wp_widgets_init();
global $wp_registered_widgets;
restore_current_blog();
wp_widgets_init();

(Note I assume your code is incomplete pseudo code and that you'll actually use more code than you listed.) 

Hope this helps.
