YMCA- policy to prevent unfairness

I want to try to get the YMCA and another local league to use an accountability system like Pop Warner has to ensure kids get the minimum required playing time.  It  is common practice for coaches to disregard the rules, and, by then, the damage is done, and only a few will complain.  Even when I did complain, the coach was good for one game then went back to his old ways.  Has anyone had experience trying to get an accountability policy going?
