It’s probably not a great idea to do something like this via client side scripting especially given the circs for wanting to do this. A filter function ought to be created to handle it.

It’s worthy of looking at with a view to creating a plugin or functions.php function, shouldn’t be too difficult to do and I might have a look later time permitting or hopefully one of the more skilled members with the BP API might suggest an approach.
