when admob ban an App, it bans the whole package name "com.yourapp" even if you created a new admob account you won't be able to use it.
Your only option is to create a new app with a new package name, also make sure that ALL the content of your App is yours or you have a copyright permission to use it (RSS feeds, websites, domains, videos, articles, photos.... etc). otherwise you'll get banned again and again until you lose your developer account for good.
