If you want to use the "private sector lense" (which I do not think is valid for a govenenent bureaucracy), there's a reason why when I've participated in M&A events, we would spend a year doing due diligence and understanding the organizational and financial structure before initiating an event.
By haphazardly doing these kinds of initiatives without even understanding regulations and laws means any potential savings will be burnt in litigation and cleaning up messes.
