If this works why would you need to restrict it to non-O weddings?  
We could use this technique to be m'vatel any kiddushin where there 
is an agunah.  From the fact that we don't use it there, I would 
assume that we couldn't justify using it by non-O.

As to why we don't use it to free agunos, I'm not familiar enough 
with the sugya.
